Enables reserving memory for saving permanently downloaded fonts
and macros, when the printer switches between this and another
interpreter. The effect is to save the memory for a subsequent
job using this interpreter.
When set to Off, all permanently downloaded fonts and macros are
cleared from memory when switching PDLs. They must be
downloaded again when the printer switches back to using the
current PDL.
When set to On, permanently downloaded fonts and macros are
stored in printer memory. You eliminate the time to download
them again when the printer switches back to the current PDL.
In PCL, this is referred to as Resource Savings.
The value 'other' shall mean not specified.
