Introduction The Epson P-80 is a portable, battery-operated printer that enables you to print anywhere you go. It adds state-of-the-art thermal transfer technology to other features that have made Epson printers so popu- lar.
The first three chapters of this manual help you set up, operate, and maintain your printer. Chapter 4 contains information on how to use control codes with your printer. Chapter 5 shows you how to combine print modes and Chapter 6 explains the printer’s graphics features.
Chapter 1 Setting Up Your P-80 In this chapter, you’ll learn how to prepare your printer for opera- tion and how to connect it to your computer. But first, take inventory. With your P-80 you should receive the items shown in Figure 1-1. They are: 1.
Figure 1-1. Unpacking the P-80 (Top view) Figure 1-2. Identifying the printer parts 4.
Covers The front and back covers are designed to keep your P-80 free from dust. It is a good idea to keep them closed when your printer is not in use. The front cover protects the print mechanism and reduces the noise level when the printer is on. The serrated edge serves as a convenient tear-off point.
Note: Before you continue, take a moment to look inside your printer. You will see a gray bar with a line and the word paper. Remove the thin transparent strip covering this bar. Paper guide As mentioned above, when the back cover is vertical, it serves as a paper guide.
Ribbon installation When you are using thermal paper, you do not have to install the ribbon cassette. With any other type of paper, install the ribbon cas- sette as described below. Chapter 3 gives an explanation of the types of paper to use. Before installing the ribbon cassette, you need to lift the front cover (Figure l-5).
Figure 1-6. Installing the ribbon 8.
4. Hold the cassette so that the exposed ribbon is on the left side and the closed ends of the ribbon holes are on top. Place the cassette over the print mechanism. Make sure the ribbon is placed in front of the silver print head. Press down and snap it into place.
Figure 1-8. DIP switches Note: Make certain the printer is turned OFF when you change DIP switch settings. The P-80 checks these settings only at power- up and it will ignore any changes made with the power on (until it is turned off and back on). Switch 1 The functions of the four switches that make up switch 1 are sum- marized in Table 1-1.
You can also access the International characters by using a control code. See Chapter 4 for an explanation of control codes and Appendix B for the appropriate code. Table 1-2. International character switch settings Country SW 1-1 SW 1-2 SW 1-3 U.S.A.

For many computers, you merely plug the printer cable into your computer. However, some computers require a printer interface card, either mounted inside or outside the computer. Check your computer installation or operations manual for details on how to connect your computer to your printer, or consult your dealer.
Chapter 2 Operation and Maintenance Your P-80 is now connected to your computer and ready for opera- tion. In this chapter you’ll learn how to use the controls and indicators on the printer to operate it correctly. You’ll also learn how to recharge the battery and maintain your P-80 to keep it printing smoothly for a long time.
POWER switch — This switch activates the power when it is in the ON position. Push this switch on and you will hear the print head prepare itself for printing. ON LINE switch — This switch allows you to switch back and forth from on-line to off-line status.
Figure 2-2. Paper control switches PAPER SURFACE switch — This switch adjusts the print head speed to improve the print quality on standard paper. Push this lever toward the front when using coarse paper; push it back when using smooth or thermal paper.
The battery needs charging when the print becomes very slow and the ON LINE light blinks. To charge the battery, first turn the power OFF. Then plug the AC adapter into the back of the printer as shown in Figure 2-3. The battery charges in six to seven hours.
Battery Replacement Your P-80 uses a nickel cadmium battery. If the red light keeps flash- ing after the battery has been charged, the battery has come to the end of its life and must be replaced. Nickel cadmium batteries are available through your Epson dealer.
Figure 2-5. Lifting the cover 4. With the battery holder cover open, locate the battery connector near the POWER switch. It is marked CN7. Unplug the battery connector noting the direction of insertion. Remove the battery with a screwdriver as shown in Figure 2-6.
5. Place the new nickel cadmium battery into the battery holder with the connector cable at the bottom. Insert the battery connector into the slot marked CN7.
Maintenance As with any mechanical device, the best maintenace of your P-80 is preventive maintenance. Here are some general guidelines to follow: 1. Keep your printer in a safe, clean location away from extreme tem- peratures. 2. Clean particles and dust from the printer with a soft cloth or brush.
Chapter 3 Installing Paper By this point, you’re probably anxious to start printing. In this chapter, you’ll learn the different types of paper your P-80 can use and how to install the paper. Then you can start to print by having the printer perform a self-test.
Remember to adjust the PAPER SURFACE switch for the type of paper you are using. For coarse paper, set the switch to RGH; for smooth or thermal paper, set the switch to SMT. Paper sizes The printer uses single-sheet paper and handles any paper the width of the platen (8½ inches) or narrower.
Figure 3-1. Loading the paper 4. Turn the manual-feed knob clockwise until the paper feeds through to the front as shown in Figure 3-1. 5. Put the power switch in the ON position if you have not done so already.
Removing the paper When you are finished printing, remove the paper by using the manual-feed knob. If your paper is almost out of the printer, you can release it by placing the lock lever in the FREE position. The P-80 Self-Test It’s time to see how your P-80 operates.
Chapter 4 Control Codes This chapter explains how a computer uses control codes to send instructions to your printer. Specifically, you’ll learn how the control codes work with the P-80. (Appendix A shows a complete listing of all the P-80 control codes.
alphanumeric characters and special symbols. For instance, 65 repre- sents the capital letter “A”, while 90 represents the capital letter “Z.” On the P-80, the graphics character set is stored at codes 128 through 159. Other ASCII numbers control computer and printer functions.
following chart shows many different ways of referring to the code for the carriage return function. Carriage return Its common name CR The abbreviation of its name 13 The decimal ASCII code 0DH Its hexadecimal ASCII code CTRL/M Its control-code name CHR$(13) Its usage in BASIC As you can see there are many different ways to refer to a single code.
You will have a better understanding of how the (ESC) codes work when you use them in your programming. Appendix A lists all the ASCII codes and Appendix B summarizes their functions. A BASIC example Keep in mind that the ASCII codes and the ESCape sequences are mostly used with programming languages.
Underline mode does not use the underline character which is prob- ably used in your word processing software. Since the underline char- acter is only five dots wide, it does not print in the space between each text character.
Chapter 5 Combining Print Modes One of the most pleasing aspects of your P-80 printer is its variety of print modes that can be combined to make different typestyles.
Figure 5-1. Main columns and intermediate positions Although each P-80 character is designed to be five or fewer col- umns wide, dots can also be placed midway between each main col- umn. This means that the dot pattern is printed twice, shifted one half dot to the right.
just over 17 characters per inch. The smaller characters allow for spreadsheets, or other work that requires compact printing, to be squeezed on an 8½-inch page. In Figure 5-3, you can see the difference in the two pitches. Pica is the default, the pitch in effect when the printer is turned on.
Print Quality Modes There are two modes that produce boldface (darker) characters which make your printout more distinctive. These modes are Double- Strike and Emphasized. Each gets its bold effect by printing overlap- ping dots as explained earlier in this chapter.
together, the one with less priority is temporarily ignored. Only when the higher priority mode is turned off, will the lower priority mode take effect. For example, suppose you activate both Emphasized and Com- pressed. Since these modes cannot be combined, the printer must make a choice.
4. When two modes conflict, the one of lesser priority is masked (not cancelled). For example, Compressed and Emphasized cannot be printed at the same time. When both are active, printing is in Emphasized. When Emphasized is cancelled, printing is in Com- pressed.
Chapter 6 Graphics Your P-80 is capable of printing special graphics characters and dot graphics, but you do need some programming knowledge to use these graphics features. This chapter is included for those who wish to design their own programs to take advantage of the printer’s graphics capabilities.
80 FOR X=150 TO 159 90 LPRINT CHR$(X)" "; 100 NEXT X: LPRINT 110 LPRINT CHR$(27)"@" Remember that you can print these characters in different pitches and weights. For example, if you want to see them in Pica, delete line 10 from your program to produce the result below.
120 130 140 DATA 134,-6,32,134,-6,149,134,-l DATA 134,152,32,152,32,152,32,134,-6,32,134,-1 DATA 137,-6,133,129,-6,133,138,0 Now that you have seen the program work, you can substitute your own DATA lines to make it print any combination of graphics characters you need.
Each time the print head makes a horizontal pass, it prints a pattern of dots. To print figures taller than 7 or 8 dots, the print head must make more than one pass. Each pass of the print head contains one piece of the total pattern, which can be as tall or short as you desire.
you can use a 2 or 3 for n 2 . A 2 in the second slot means reserve 2 groups of 256 dots (512) plus whatever is in the first slot and so on-up to 3 times 256 (or 768) dots.
Figure 6-1. Labelling elements Decimal sum of the desired pin pattern Figure 6-2. Element combinations 4 4.
The place values in a binary number are powers of two. Figure 6-2 shows how you use a decimal sum—74—to fire a particular pattern. If you try adding several numbers together, you’ll see that with this sys- tem you get no duplicates.
The width of one space invader in this program is 12-dot positions (plus one blank space). This means that 13-dot positions are enough data to describe a single invader. We will use a series of 20 invaders for this program. This gives you a total of 260 (13 x 20) dot positions for data.
Note: If you don’t understand how the numbers were determined, refer to Figures 6-1 and 6-2. It takes a while for your system to compute the data so be patient. Your printout should look like this: Run the program once more, but this time use Double-Density mode.
WIDTH statements Many computer systems automatically insert a carriage return and a line feed after every 80 characters. This insertion usually causes no problem with text, but it can spoil your graphics. In the Graphics mode, some systems insert the control codes after 120 columns, which may be in the middle of a line.
Figure 6-4. Result of incorrect program Once the graphics mode is in effect, every number sent to the printer is interpreted as a dot pattern and printed on the paper.
l Do not put any other commands between the graphics command and its data. We hope this example helps you identify errors if one of your own programs gives you unexpected results.
Appendix A ASCII Codes and Character Sets This appendix provides information about the ASCII codes used on the P-80 printer. The first section shows the available codes between 0 and 32 with their decimal and hexadecimal numbers, abbreviations, and the control keys associated with each code.

Appendix D Using Your P-80 with the Geneva™ PX-8™ Since your P-80 is a portable printer, it is a suitable companion for any portable computer. With the P-80, you can print anywhere, thus eliminating the need to wait until you have access to a desktop printer.
Note: If you do not use a dot command, or omit page numbers, as described above, the P-80 stops printing near the bottom of the page. Although printing has stopped, the printer and the com- puter remain in the print stage. To end your print session, in WordStar, press the P to stop print and then Y to abandon print.
Figure D-l. Connecting the Geneva to the P-80 Be sure you have properly connected your printer and it is ON and on-line before you begin to print. If the P-80 won’t respond to any of the computer’s print commands, hold down CTRL and press STOP on the Geneva.
