  • Page 12: Covers

    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 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 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.

    If you happen to lift the cover off completely, replace it by positioning the hinge at each end of the cover over the hinge posts at the front of the printer. The hinges allow you to easily open and close the cover without removing it.

    The manual-feed knob is used to advance the paper manually. It is located on the right side of your printer. When your printer is packed, the knob is pushed in flush with the right side. To bring it out, push the center of the knob in and release it.

    Switch 2 The P-80 uses the RS-232C serial interface to communicate data from your computer to the printer. The switches which make up switch 2 are used to set up the proper serial communications for the RS-232C serial port.

    The light glows red when the printer is on-line, and when the light is off, the printer is off-line. If you turn the power ON without any paper in the printer, the ON- LINE light will not glow, even if you press the ON-LINE switch.

    Paper-out sensor The P-80 is equipped with a device that warns you when the printer is at the end of the paper. When your paper reaches the end, the ON LINE light goes off and printing stops.
  • Page 24 Once you unplug the adapter, let the printer run on its own until it needs recharging. Recharging the battery more often than needed can weaken it.

  • Page 25: Battery Replacement

    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.

  • Page 28: Maintenance

    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.

  • Page 29: Installing Paper

    Paper Types The type of paper to use with your P-80 is thermal paper. It will give you the best quality print. Since thermal paper is heat-sensitive, you do not need to use the ribbon cassette.

  • Page 33: 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.) If you are going to use your printer with commercial software pack- ages, it is not necessary for you to read this chapter.

  • Page 34: Using Control Codes

    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.

  • Page 35: Ascii Codes As Chr$(N)

    So many features have been added to printers that even 256 ASCII codes are inadequate if only single-code CHR$ instructions used. Because of this, the logic of the P-80 has been designed to under- stand special sequences of control codes, the ESCape code sequences.

  • Page 36: Basic Example

    Different computer systems access the printer in different ways. For example, most computers that use Microsoft BASIC send PRINT or LIST commands to the printer by adding a leading L to a screen com- mand: LPRINT, LLIST. Your computer may not use these commands.

  • Page 38: Combining Print Modes

    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. You access these print modes through programming languages such as BASIC. You can also access them through your word processing pro- gram, if your program allows you to insert print commands in the text (for example, Portable WordStar’“).

  • Page 39: Print Pitches

    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 umn. This means that the dot pattern is printed twice, shifted one half dot to the right.

    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. P i c a C o m p r e s s e d Figure 5-3.

    Roman characters. Any computer system can select Italic mode without software adjustments. The P-80 has a built-in Underline mode making it easy for you to underline anything. You can underline characters or blank spaces as demonstrated in Chapter 4.

  • Page 42: Mixing Modes

    For example, suppose you activate both Emphasized and Com- pressed. Since these modes cannot be combined, the printer must make a choice. In this case, the printer is assigned higher priority (see Table 5-l).
  • Page 43 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.

  • Page 44: Graphics

    Check your computer’s documentation to see if it contains this feature. Graphics Characters The P-80 contains a set of special graphics characters which are the same graphics characters available on the Geneva graphics characters are accessed with ASCII codes 128 through 159. If your computer cannot access codes greater than 127, you will not be able to use the graphics characters.

  • Page 46: Dot Graphics

    If you plan carefully where you want the dots to appear and use your computer to give the printer the proper instructions, your P-80 will generate nearly any pattern or figure you wish.

  • Page 47: Graphics Mode

    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 total pattern, which can be as tall or short as you desire.
  • Page 48 Labelling Elements Once you put the printer into Graphics mode, your next step is to tell the print head which elements to fire in each column. You do this by sending numbers via the CHR$ function. Each number that you send represents a unique combination of dots.

    Semicolons and command placement After the graphics command is issued, every number sent to the printer is interpreted by the P-80 as a dot pattern and is printed on the paper. Therefore, you must be careful where you put the graphics command in your program, and you must not put another command between the graphics command and the graphics data.

    To print the desired results from some of these programs such as WordStar, some modifications may be necessary. For example, the P-80 stops printing when no paper is in contact with the paper-out sensor (a reed switch located on the paper guide).

  • Page 67: Connecting The Geneva To The

    If a particular function exists on WordStar, but not on the P-80, the printer will ignore the command to execute this function. For exam- ple, if you want to print in Elite, the P-80 will ignore this command since it does not have this capability. Before using print commands in your software applications, check to see that they are available on the P-80 by consulting Appendix C in this manual.
