Introduction “But do I REALLY have to take a course on ‘How to operate a printer’ to use this one?” No - not if you only want to use it for mundane printing.
X.
The Starting Line Chapter 1 The Starting Line This important chapter shows how to unpack, set up, and test your new printer. Read it before you get into trouble. The time spent will be your best investment since buying the printer itself. Counting the Parts Open the box and carefully and remove the contents.
Chapter 1 With the printer facing you, as shown in Figure 1-2, grasp the side and pull straight up. Very easy. To replace the lid, procedure. lid on its left top just reverse the Figure 1-2 Locate the 2 shipping screws, shown in Figure l-3. These screws are used to protect the MX-70 from damage during shipping.
The Starting Line Installing the Ribbon Position the printer with the Epson label (front) facing you. Locate the paper bail (the moveable metal bar with numbers l-80 on it - see Figure l-3) and push it toward the back of the printer, against the metal platen.
Chapter 1 Incorrect Ribbon Incorrect Correct Figure 1-4C Wind the ribbon tight again with the little plastic knob, and it’s all set to go. You may notice a sticker with the words EXCHANGE TIMES pasted on the ribbon cartridge. This is a remnant of an early plan to refill the cartridges when the ribbon wears out.
The Starting Line Opening the Case To locate the wiring terminals, we have to open the case. The lid should still be off. Remove the roller knob by pulling straight out, with firm but steady pressure (Figure l-5). Figure 1-5 Turn the printer upside down on a soft surface.
Chapter 1 Figure 1-7 Take a minute to gawk at all the stuff in the box. Wow! As Custer said, “Look at all those . . . ” well, anyway. Wonder how they sell it as cheap a they do? (Hope it prints as good as it looks.) The Epson Connection Figure l-7 shows the location of the moveable wire.
The Starting Line When in Doubt, Bluff If you have an Apple, move (if necessary) the short white wire located between them to the red terminal (as in red apple). If you have any other computer, hook it (for now) to the white terminal. If we guessed wrong, nothing will be harmed.
Chapter 1 To install the rack, simply spring the wires a bit so they pop into the holes in the printer frame, as shown in Figure l-8. Figure l-8 Feeding the Paper The MX-70 accepts pin-feed paper between 4” and 10” wide. Both the left and right hand tractors are adjustable to match the spacing between the drive holes.
The Starting Line Pull the paper bail forward. Open both tractor covers and center the paper guide roller between them (Figure l-10). Tractor Position Lock Lever Paper Holding Cover Paper guide roller.
Chapter 1 Adjusting for Paper Thickness The MX-70 can print on all types of pre-printed multiple copy forms and carbons, as well as ordinary printer paper. The 7 position thickness control lever (Figures l-10 and l-11) moves the print head closer to or farther from the paper, changing the print quality somewhat.
The Starting Line Where is all the motor noise? How about some big levers, lights, and alarms? Looks like dynamite in a small silent package! The POWER light should be lit. Press the FEED button several times and watch it advance the paper. This doesn’t look at all complicated.
Send it a Message Chapter 2 Send it a Message The MX-70 printer is smart. It knows how to follow instructons. Any Code Devised by Man Can be Broken by Man Many instructions are sent to the printer. Every letter, number, and other character travels from the computer through the printer cable in the form of a code made up of numbers.
graphic and other features they will have to resort to POKEing codes or some other devious means, and are referred to their own computer’s reference manual. The Philosophy This is a book about a printer, but since a printer without a computer is worthless, we must also talk about computers.
Send it a Message may be connected to Port #l) to the code stream sent to the video screen. PR#0 “unhooks” Port #I from the video signal chain by sending ALL printing only to the screen. Most other BASIC S use a special word such as LPRINT to send codes directly (and exclusively) to the printer.
Chapter 2 There are many parallel interface cards made by other manufacturers. Be sure the card you purchase is designed to work with the MX-70. Testing the Hookup The time has come to see if all this hardware works. Whatever your computer is, now’s the time to be sure it’s hooked up to the printer.
Send it a Message 10 PRINTTAB (14) ; “GREETINGS FROM THE GRAPHIC” 20 PRINTTAB (22); CHR$ (14); “MX-70’ 30 PRINTTAB (22) CHR$ (27) “K” CHR$ (60) CHR$ (0); 40 FOR I=1 TO 25 STEP .
Chapter 2 There is a lot happening, so we’d better disect the program (like a frog) to learn all about it. Type LIS T (TRS-80 etc. use LLIST) to LIST the program on paper. Push the FEED button to roll the printout past the lid. Tear it off and keep it handy so we can study the program as we go along.
Send it a Message Not all codes actually print on either the screen or the printer. Most special or “control” codes don’t really PRINT anything, even though we must precede them with a PRINT to “push them down the line” to the printer.
Chapter 2 We send the special code CHR$ (27), which means “<Escape>,” down the line immediately preceding a control code that needs that <Escape>.
Send it a Message Line 50 actually sends the messages down the line to the printer. The expression inside the CHR$ function looks complicated, but that’s just to keep your atention. Observe its form, but ignore its contents. We’ll have to study the whole manual to find out how to generate such a pretty line of graphics.
Chapter 2 Special ‘Escape’ Codes CHR$ (27) - The BASIC ASCII combination for “Escape.” (Special code used with letter codes) “K” - The letter “K.
More Print Control Commands Chapter 3 More Print Control Commands That last chapter was a heavy one, but it gave us a good overview of many MX-70 features. In this chapter we’ll explore a few of them in more detail. As before, CHR$ is the magic wand.
Chapter 3 Don’t forget, double WIDTH mode is automatically turned off at the end of each line, unless that line ends with a semicolon (;). If we want to print a very long line consisting entirely of double-width characters, the program lines holding the parts of that message must each have a trailing semicolon.
More Print Control Commands It may take a little practice to get the paper positioning perfect. We need to be able to do it right, especially for matching lines and boxes on pre-printed forms such as invoices, bills of sale, purchase orders and the like.
Chapter 3 The Form Feed - in Basic Software Let’s modify our program to print only 10 lines, then have it automatically roll the paper up to the next TOE CHR$ (12) means “Feed Form to TOF.” Make the program read: 9 PR #1 20 FOR N = 1 TO 1 0 3 0 PRINT N 40 NEXT N 45 PRINT CHR$(12 ) 49 PR # 0 (Apple) (TRS use 12+128=140) (Apple) and RUN.
More Print Control Commands Let’s all read the following “Philosophy” carefully. It is absolutely vital that we understand the concept of the “endless loop” to use any printer for serious business type applications.
Chapter 3 Now we are all on the same channel, and the printer hasn’t forgotten where the Top Of Form belongs. When the floor is strewn with paper and the point has been made, you may hit CTRL-C, (or BREAK) and let a silent smile creep across your ugly puss.
More Print Control Commands 30 NEXT N 39 PR #0 (Apple) and RUN. OK gang. It’s different strokes for different folks. Users who can see their printer merrily printing numbers out to column 75 can give their computer a little pat on the - ah, keyboard.
An Introduction to Dot Matrix Printing Chapter 4 An Introduction to Dot Matrix Printing (Subtitled, “Does a Dull Title Make a Topic Dull?“) My Computer Can’t Do High Resolution Graphics! Correction, your computer can do high resolution graphics - on the MX-70 printer.
Chapter 4 Each pin is driven by a “gun,” or electromagnet, which “fires” when told to do so by the electronics inside the printer. The printer electronics responds to those ASCII code instructions we send from the computer in the form of “ASCII numbers.
An Introduction to Dot Matrix Printing Figure 4-3 For a complete listing of all the standard MX-70 characters, look at the self-test printout from Chapter 1. It’s right there, hanging on your wall, isn’t it? How it all Lays out on Paper We have seen that all the characters are a uniform 7 dots high.
Chapter 4 So what does all this higher mathematics have to do with graphics? Just this. If we are to create high-resolution graphics on the MX-70, we have to eliminate the “dead space” between letters by changing the automatic line spacing to some value less than l/6 inch.
An Introduction to Dot Matrix Printing Line 10 contains the following 2 distinct commands: 1. An <ESC> “A.” It opens Pandora’s box to let us set the vertical line spacing accurate to a single DOT - 1/72nd of an inch. Mercy! 2. A CHR$ (##).
Chapter 4 Check the printout and find where spacing is 12. Doesn’t that look more like what we’re used to? Now look at 24 dot spacing. Aha! It’s double spacing. By sending the high- powered command in line 10, we can plug in our own value of S and make the printer give us just about any spacing we want between lines (up to 85).
An Introduction to Dot Matrix Printing There are several code numbers already reserved for special things. If we look closely at the printouts from this chapter, we can see that the spacing when the f.
Chapter 4 Type in this NEW program: 9 PR #1 (Apple) 10 PRINT CHR$ (27) "A" CHR$ (0) (or 0+ 128) 20 PRINT "UNDERLINE" 30 FOR U=l TO 9 : PRINT CHR$ (95); : NEXT U 40 PRINT CHR$ (27) "2" 50 PRINT "WORKS" 59 PR #0 (Apple) and RUN.
An Introduction to Dot Matrix Printing Line 40 returns line spacing to the normal 12 DOTS Line 50 PRINT S more text to show that all is normal and that’s plenty to think about in this chapter.
Graphtrax II Chapter 5 Graphtrax II Caution - Entering High Resolution Space To create graphics on the MX-70, we must enter a completely new mode: the GRAPHICS MODE. In this mode, pre-defined characters do not exist - only dots. We create our own characters or images by arranging the dots however we wish.
Chapter 5 The Saki flowed like melting snow from Mt. Fuji when they contrived that wild scheme. Let’s see if we can wring it out. Suppose we want to shoot 100 columns of graphics to the printer, on one row. What numbers would we use for N1 and N2? CHR$ (l00) CHR$ (0) for 100 columns Ok, so we got lucky.
Graphtrax II We’ll label these top 8 pins as follows: 128 - 0 TOP 64 - o 32 - o 16 - o 8- O 4- o 2- o l- o BOTTOM o (Ninth pin not used) From now on we will refer to the second pin (pin 1 above) as the “bottom” pin when using graphics. Why not label them 1, 2, 3, .
Chapter 5 Wow! A jackpot. Using the bottom of an old Coke bottle as a magnifier, we see that each column is 7 dots high. 50 columns of 7 rows of dots. The sum of the bottom 7 pin numbers is 1 + 2 + 4 .
Graphtrax II Now for the Bad News Before racing off to create a HI-RES forgery of the Mona Lisa, be aware that the above is how is it SUPPOSED to work. Reality is brutal - there are some exceptions to almost every rule. Code numbers 9 and 13 for the Apple, and 0, 10, 11, and 12 for the TRS-80 create havoc when used as N1 or N2.
Chapter 5 TRS-80 Model I: 10 LPRINT CHR$ (27) "K" CHR$ (50) CHR$ (2); and RUN. Figure 5-2 Press CTRL-C or BREAK to stop. Very impressive. Note that we are not printing the slash character (ASCII number 47); but are positioning the dots one at a time.
Graphtrax II 100 DATA 4,4,4,4,4,61,71,70,60,4,4,4,4, 4 110 DATA 72,79,89,107,77,73,127,89,73,79,73,73,73,7 3 120 DATA 16,112,54,17,81,17,126,16,48,80,16,16,16,1 6 TRS-80 Model I: 40 LPRINT CHR$ (27) “K”CHR$ (14) CHR$ (2) ; and RUN.
Advanced Graphics Chapter 6 Advanced Graphics Firing Pins at Seven Paces The MX-70 allows any computer to control the firing of its 8 active pins by simply sending ASCII code numbers between O-255. Conversely, these 256 code numbers are sufficient to control all 8 pins.
Chapter 6 Line 10 sets the top-to-top line spacing at 7 dots. Lines 20 and 30 KICK the printer into graphics mode. N specifies the number of graphic columns. By making it a variable, we can easily change it later, right within a program, to print graphic lines of different lengths.
Advanced Graphics The Data Bank HI RESolution graphics requires lots of DATA. It comes with the territory So, what should our DATA lines look like? How should we format them so contain the information we need? What information do we need? they ASCII numbers O-127 are used to specify the firing combinations for the 7 pins.
Chapter 6 40 FOR G=l TO N 50 READ X 120 NEXT G 130 PRINT The numbers READ into X are the actual pin firing instructions. If X falls in the range 0 - 127, we print it in line 60 below.
Advanced Graphics List and recheck the completed program to make sure everything is correct: 9 PR #1 (Apple only) 10 PRINT CHR$ (27) "A" CHR$ (7) 20 READ N : PRINT TAB (10); 30 PRINT CHR$ (2.
Chapter 6 All That Work for one Line? We shouldn’t complain too loudly. It works, and no one said creating graphics was easy. Our current “universal” program can only handle one line of DATA, and it’s becoming increasingly apparent that HI-RES graphics requires lots of lines of DATA.
Advanced Graphics Rowdy Characters Add the following lines: 1070 DATA 44,-12,8,-32,12 7 1080 DATA 39,-17,0,64,96,112,120,124,-12,127,124 , 120,112,96,6 4 and RUN. Figure 6-4 Oops! There’s trouble in River City. Fortunately, we’ve seen these same control code problems before.
Chapter 6 A Confession Line 1070 was artificially injected into this conversation to illustrate some of the problems the rebel character codes can cause. We’re playing for real now, so change line 1070 to: 1070 DATA 44,-12,0,64,112,120,124,127,127,15,7,67,99,51,3 , 63,123,71,3,3,71,123,63,3,51,99,67,7,15,127,127 , 124,120,112,6 4 and RUN.
Advanced Graphics Figure 6-6 It was worth it! We now have all the tools needed to design and print our own graphics. Be sure to save the finished program as we will use it in the next chapter.
The Final Push Chapter 7 The Final Push Only masochists failed to SAVE the final program from the last chapter. We’re now going to delete all its DATA lines and reconstruct it for more universal applications. DELETE LINES 1000-1080. Mix and Match We are obviously amazed at the MX-70’s graphics ability.
Chapter 7 No, it’s not another demon. It is a “broken signboard” that needs a text type LABEL in the middle. The finished graphics/text display will be printed in these three parts: 15 columns of graphics 30 columns of text (5 characters) 15 columns of graphics Now we have to mix and match graphics and text on the same line.
The Final Push Figure 7-4 Nothing to it! NOTE: As long as semicolons are used to delay the line feeds, graphics and text are easily mixed on the same line. New lines can be started by simply adding line feeds with PRINT statements as shown in line 140.
Chapter 7 If we really understand what we’re doing, the 7-bit limitation can be overcome. Apple users try: 140 GOSUB 20 : GOSUB 20 : PRINT 150 DATA 23,-23,127,127,-127,127 and RUN. Now we are getting somewhere. Instead of trying to print the entire line in one shot, we hooked two print routines together with a semicolon.
The Final Push Apple Stew I’m afraid that Apple users wound up with a slightly different result, even though the 300 should be valid for the current program. Figure 7-7 This appears to be a conflict among the Apple, the interface board, and the MX-70.
Chapter 7 Pictogram Let’s see if we can parlay strings of graphic characters into a useful format. Enter this NEW program. 9 PR #1 (Apple) 30 FOR I=1 TO 5 : READ A(1 ) : NEXT I 40 DATA 8,107,92,107,.
The Final Push The DATA for the population figure is READ into array A in line 30. Each figure is printed in SUBroutine 300. DATA line 130 determines how many figures are printed on each row. We have the makings of a horizontal bar graph, but it needs some trimmings.
Chapter 7 10 PRINT TAB(23)CHR$(14)"POPULATION PROJECTION" 140 PRINT : PRINT TAB(37); : GOSUB 300 150 PRINT "( = 1,000" and RUN. Figure 7-10 That’s plenty for this chapter. Code Summary PRINT CHR$ (9) “255H” - Allows Apple users to print past column 255 without heartburn.
Using the HIRES Screen Dump Program Chapter 8 Using the HIRES Screen Dump Program Should I Study This Chapter? Epson dealers can supply a machine language “screen dump” diskette for Apple users with 48K disk systems. It permits creation of exotic HI-RES graphics on the Apple screen, then dumping them, dot for dot to the MX-70 printer.
Chapter 8 Load the demo disk into drive 1 and boot the system. The HELLO program will automatically load and execute. After a brief commercial from the copyright holder, the program asks: IS THE PICTU.
THIS PAGE HAS BEEN AMENDED Using the HIRES Screen Dump Program DISNEY CHAR SCHEMATIC PORTRAIT CHESS Follow the Yellow Brick Road The HELLO program guides us through the actual process of printing the pictures. It’s completely self-explanatory (as every confusing technical book says), but here’s some step-by-step guidance.
THIS PAGE HAS BEEN AMENDED Chapter 8 For now, let’s try REVERSE: R <RETURN> The last question is: WHAT IS THE PRINTER SLOT # ? (1-7) ? Double check to see that the printer is ON and loaded with paper. Our printer card is in slot I, so: 1 <RETURN> Now we just sit back and relax while the MX-70 does its thing.
THIS PAGE HAS BEEN AMENDED Using the HIRES Screen Dump Program Go ahead and try the different print options with PORTRAINT, large and small, reverse and regular. Print several of the pictures. Instead of PORTRAINT type the name of another one. Most load into the HIRES page “low memory.
Chapter 8 Not too shabby for rank amateurs. Here’s what happens: Line 10 clears the screen. Line 20 selects the “low memory” HIRES page. This part of memory is used for high-resolution graphics, while text is stored on a different ‘page’ of memory.
Using the HIRES Screen Dump Program 50 R=30 * (~- S I N ( A ) ) and 50 R=80 * COS(3 * A/4) (Change line 40 to 40 FOR A=0 TO 26 STEP .01) and RUN. Figure 8-3 When you see one you like, add this screen dump “linking routine” to hook the BASIC program to the HIRES program: 80 POKE 10,76 : POKE 11,00 : POKE 12,96 90 PRINT “BLOAD EPSON.
Chapter 8 Figure 8-4 Lines 80 and 90 are straight out of the HIRES INSTRUCTIONS program listing. They load the screen dump routine without leaving the BASIC program. As indicated in the HIRES instructions, we use the machine language routine named EPSON.
Using the HIRES Screen Dump Program “...Never give up!” Commencement Address Now that we’ve learned everything there is to know about the MX-70 and HIRES graphics, our education is ready to begin. I’d enjoy hearing from you and seeing some of your artistic creations.
APPENDIX A Appendix A ASCII Charts for MX-70 79.
Appendix A This is the standard ASCII character set. The codes that are highlighted are understood by the MX-70 printer. The rest are for your information only, and serve no function on the MX-70 printer.
Appendix B Control Codes ASCII *2 FUNCTION Returns line spacing to 1/6”. 8 10 %12 13 14 20 27 *:65 *67 *75 ASCII “K.” Initiates graphics mode. Cancels last character entered in text mode. Line Feed (LF). Empties printer buffer. Form Feed (FF). Advances paper to the next top of form.
APPENDIX C Appendix C Character Set 83.
Appendix C 84.
APPENDIX D Appendix D TRS-80 Differences This MX-70 Manual is designed around the Apple II for reasons discussed in Chapter 2. Fortunately, TRS-80 users can use it successfully by following the notes and suggestions in this appendix and throughout the text.
Appendix D We can get around this limitation by POKEing the code numbers directly to the printer buffer, foiling BASIC’s attempts to intercept it. The location we POKE is 14312, so use: POKE 14312,0 In fact, we could use POKE to send ALL our graphic codes, but this approach creates timing problems between the printer and computer.
APPENDIX D The Model III does not share the Model I’s problem sending code 0. Nonethe- less, another way to send codes to the printer is: OUT 251,# where # represents the code we wish to send. If this creates timing problems, we may need to test the status of the printer before sending it each code number.
APPENDIX E Appendix E Use with Atari Using Atari 800 Computer with Atari 850 Interface Lines ending with a semicolon cause the Atari to automatically “pad” the rest of the line with spaces until it is 40 characters long, when using LPRINT. Therefore, it is advisable to avoid LPRINT.
APPENDIX F Appendix F Use with Apple Apple Integer Basic The MX-70 is activated by ASCII code numbers from O-255. The easiest way to send these codes in BASIC is via the CHR$ function, a feature not supported by Apple Integer Basic. In theory the codes could all be POKEed from BASIC but it doesn’t seem to be a practical option.
Appendix F Tricky Codes Most Apple users will encounter difficulty when using codes 9 and 13 in ESCAPE sequences and the graphics mode. To corral these and other rowdy codes, we can POKE the ASCII code numbers directly to the printer driver.
APPENDIX F The prior code sequence also diverts all output to the printer ONLY! The video display is disabled after the CTRL-I # N sequence. The way to bring it back is by: <CTRL I> I In the process, the printer width defaults back to 40 columns.
APPENDIX G Appendix G Special Notes on Other Computers/Languages/Interfaces Interfacing The MX-70 is designed to interface directly with parallel printer computers like the Apple II and the TRS-80 Models I, II, and III. RS-232, IEEE 448, and other interfaces are not factory supported.
