Printing tasks
   

Source

Printing by Source means you choose a specific tray from which you want the printer to pull paper. The printer tries to print from this tray, no matter what type or size is loaded in it. If you choose a tray that is configured for a type or size that does not match your print job, the printer does not print automatically. Instead, it waits for you to load the tray you chose with the type or size of paper for your print job. If you load the tray correctly, the printer begins printing. If you press HP 3550 3700 checkmark Source, the display allows you to choose other trays.

NOTE

If you have difficulties printing by Source, see Priority for print settings.
