Compatibility Modes

The printer’s parallel port supports ECP mode and IEEE 1284 bi-directional mode. If your computer’s parallel port is not compatible with one of these modes, the printer may not print at all or it may print corrupted data.

To correct for this:

1Enter the printer’s Maintenance menu and change the ECP setting to Disable (see Changing the ECP Setting under Printer Menus in the Printer Control section of the User’s Guide).

2If there is still a problem, enter the printer’s Level-2 menu and change the Bi-Direction setting to Disable (see Changing Parallel Interface Menu Settings under Printer Menus in the Printer Control section of the User’s Guide).
