Printer (1) is provided with a mode to edit and print forms without reference to or interruption of a host computer and with immediate printing of one or more of the forms. Page data for the forms is preferably stored in flash memory (21) in a high level printer language. Preferably, at initiation of the forms mode at least the first listed document is immediately prepared by the control data processor (17) of the printer in bit mapped form for printing. Documents can be listed on the control panel by name for ready selection for printing.
