Introduction
Several HP LaserJet printers have mass storage capabilities for
storing fonts, macros, electronic forms, and other information.
Printers such as the HP LaserJet 4000 and 5000 series printers have
an optional disk drive. The HP LaserJet 4000, 5000 series and some
other printers support flash memory, which is non-volatile memory
contained in modules that are inserted into the printer's SIMM/DIMM
slots. Preferably, the printer's mass memory is managed by a
host-based mass storage application that supports interaction
between host software and the printer disk and/or flash memory.
However, users in some environments might not have a mass storage
management application. The PJL file system commands described
in this chapter are provided in order to make use of printer- based
mass storage when a mass storage management application is not
available. The PJL file system commands described in this chapter
are used the same on both types of printer mass storage (printer disk
drive and flash memory).
Note For information about creating a host-based mass storage
management application, contact your HP support representative.
Note For information about products newer than those included in this
book, see the Printer Job Language Technical Reference Addendum,
which includes product-specific information about newer products, as
well as commands and variables added to PJL to support these
newer products.
