6Troubleshooting

To verify that your computer can communicate with the printer, use one of these methods:

■If you have a Macintosh, make sure you have the correct driver installed and that you have selected the printer in the Chooser. If the printer's name does not appear in the Chooser, your LocalTalk or EtherTalk connection may be faulty. (See also “Printer doesn't appear in the Chooser” on page 6-7.

You can use the Print Directory command to send a file to the printer without using an application. If the communication link between your computer and the printer is working, the printer produces a directory listing of the active window on the desktop.

■If you have a PC, use this DOS ECHO command:

ECHO %! > port

ECHO SHOWPAGE[CTRL-D] > port

Where [CTRL-D]indicates pressing the D key while holding down the CTRL key. Substitute the name of the printer port (for example COM1:, COM2:, LPT1:, LPT2:) for the variable port in this command. For example, if you are testing a parallel connection on LPT1, type:

ECHO %! > LPT1:

ECHO SHOWPAGE[CTRL-D] > LPT1:

If the communication link between your computer and the printer is working, the printer ejects a blank page. If this works, but you cannot print from your application or through Windows, make sure that the appropriate driver is installed and that you have selected the printer correctly.
