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 product is turned on.
● Send permanent resources to the product only at the beginning of a print job and not while the
product is printing.
NOTE: Overusing permanent resources or downloading them while the product is printing might affect
product performance or the ability to print complex pages.
