The PostScript printer description (PPD) file for the queue may be inappropriate for the document. For each queue, the print server uses the PPD file for the first printer attached to the queue. If you attach subsequent printers that have different capabilities, documents that require those capabilities may not print, even when they are assigned to the correct printer. Create a separate queue for the printer you want to print to and try printing again.
Check the Queue Monitor for the queue to make sure the print job is not on hold.
If no other printer is available, make an attached printer visible on the network. Have the user print directly on the printer by selecting its name in the Chooser or in the printer-selecting software (for Windows).
If the user is printing binary data, make sure that the "Allow binary data" checkbox is selected in the General panel of the Print Queue settings window and that the printer supports printing binary data. Some older printers don't support printing binary data.
If the user still can't print the document, consult the manual that came with the printer and the documentation that came with the program.
