Are the pertinent APPLETALK, IPX, and/or TCP/IP parameters set up correctly?
Make a test print in PostScript mode. Note: These parameters do not appear on a test print made in Raster mode. You can also verify printer/network parameters using a “telnet” session. Restart (power cycle) the printer. Under some circumstances the printer may lose network communications with the host and not regain them until reinitialization. Some parameters that are downloaded to the printer do not take affect until you restart the printer. You may want to reset the printer to factory defaults using the printer’s front control/display panel. Refer to the printer’s Operator’s Guide, Chapter 3.
