    ASCII Codes and Character Fonts This appendix provides information about the way the ASCII codes are employed on the FX printers and about the character fonts associated with those codes. The first section summarizes the codes. The second section displays, in ASCII order, the decimal number, the hexadecimal number, a printout, and an enlarged dot matrix for each character in the two fonts that you can access directly: the Roman font for the USA character set (decimal...

    Control Codes in Numeric Order You activate an FX control code by using LPRINT CHR$(n), where n is the number in the decimal column below. When the ESC column contains a dash, you use only CHR$(n) but when ESC is written in this ESC column, you must precede the CHR$(n) with CHR$(27).

    Epson Model Differences In this discussion of software and hardware differences between the MX III, the FX and the RX, the command name (backspace, vertical tab, etc.) is that of the most recent model which carries it. CHR$(8) - Backspacing On the MX III in Expanded Mode, moves the print head to the left one Pica position.
  • Page 45 CHR$(15) - Compressed Mode selection On the MX III, prints 132 characters per 8-inch line. On the FX-80 and RX-80, prints 132 characters per 8-inch line, but can print 137 characters if the right margin is changed. On the FX-100 and RX-100 prints 233 characters per 13.6-inch line.

    Defaults and DIP Switches In this Appendix we list the default settings for your printer, show- ing which settings you can change and the way you can change them. Some of the defaults can be changed by using DIP switches; the sec- ond section illustrates and discusses those defaults.

When it is OFF, CHR$(7) or paper-out doesn’t sound beeper. For printer detected error other than paper-out sensing (for which switch must also be set), the beeper will sound regardless of the setting of switch 2-2.
  • Page 56: F Troubleshooting

    This appendix approaches troubleshooting from several directions. The first section uses a columnar format to match solutions with prob- lems. Other sections cover beeper error warnings, hexadecimal code dumping, coding and seven-bit solutions, and specific solutions for several popular personal computer systems. Problem/Solution Summary The left column below will help you in identifying the source of your problem and start you on the way to finding a solution.

In these cases use the following method to change your printer initialization code to a number that is not used in the program.

    QX-10 solutions There are two types of computer-printer interface problems that you owners of Epson QX-10s may need to address. The first is making a width statement when a line is to be more than 80 characters wide. The second is changing any occurrence of the number nine to some other number.

    By using the character form of some of the numbers, you can shorten the command string. Table G-2 shows some convenient char- acters to be used for the various combinations.

  • Page 76: Customizing The Fx

    Customizing the FX You can adapt your FX to fit a variety of needs. You can alter the print capability both by hardware switches that change default condi- tions and by software codes that activate or deactivate different print modes. In this Appendix we show you a few typical applications and a few adjustments that you may want to make to your printer.
  • Page 77: Basic Program Listings

    Keep in mind that this puts extra wear on your ribbon and slows your printing speed. A few word processing programs support the FX’s Proportional Mode. Since there is no DIP switch for this mode, consult your pro- gram’s manual for instructions on activating Proportional printing. If you wish to use right-justification with Proportional, be sure that your program can do so.
