HP LaserJet 4250 - Manual (Page 262)

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 Over-using permanent resources or downloading them while the printer is printing might
affect printer performance or the ability to print complex pages.
