If it does not, you may need to change the internal setting of the computer’s parallel port for a parallel printer (or serial port for a serial printer). To do this, use the MS-DOS MODE or SETMODE command. See your printer manual and the MS-DOS Reference Manual for more details.

5.Many application programs (such as word processors) must be set up properly before they can use a printer. Check your program manual to see what customizing may be required.

6 . If you are using an application program that requires a printer driver, make sure the driver is installed properly. See your application program manual for instructions. Also see your printer manual for additional instructions on using your printer with application programs.

7 . Try running the Printer adapter diagnostics test if you have a parallel printer, or the Communication adapter test if you have a serial printer. Appendix C describes these tests. If the test indicates an error, contact your printer dealer.

Option Card Problems

If you install an option card and it is not functioning properly, check the following:

1.Is the option card installed correctly? The most common problem with option cards is a loose connection. Make sure the card is well-seated in its slot. Check the installation procedure described in Chapter 5 and also see the instructions that come with the card.

2.Did you set the necessary DIP switches or jumpers on the option card? See the card’s manual for instructions.
