9 PJL File System Commands Introduction Several HP LaserJet printers have mass storage capabilities for storing fonts, macros, electronic forms, and other information. The HP LaserJet 4000 series, 5Si, 5SiMx, and 5Si Mopier printers have an optional disk drive. The HP LaserJet 5, 5M, and 4000 series 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 so as 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. The PJL file system consists of eight commands: s FSAPPEND s FSDELETE s FSDIRLIST s FSDOWNLOAD s FSINIT s FSMKDIR s FSQUERY s FSUPLOAD These commands are described on the following pages.
