It may take a while before the printer will print out your print job. Also, certain applications can generate large PostScript files which can take several minutes to process. The printer is configured correctly. DO NOT play with any of the buttons on the printer. Check the printer queue before sending the same print job again.
Complicated documents take a while to print.
This printer can only print 1 Meg. files. Larger files will be truncated. If there is no paper in the printer, then maybe you should not be printing so much. DON'T print documents unless they are worth printing. You are wasting paper and toner.
