HP LaserJet 5200 Printer series - Manual (Page 190)

Saving resources (permanent resources)
Utilities or jobs that you download to the printer sometimes include resources (for example, fonts,
macros, or patterns). Resources that are internally marked as permanent remain in the printer memory
until you turn the printer power off.
Use the following guidelines if you use the page description language (PDL) ability to mark resources
as permanent. For technical details, see an appropriate PDL reference for PCL or PS.
● Mark resources as permanent only when it is absolutely necessary that they remain in memory
while the printer power is turned on.
● Send permanent resources to the printer only at the beginning of a print job and not while the printer
is printing.
NOTE: Overusing permanent resources or downloading them while the printer is printing might affect
printer performance or the ability to print complex pages.
