Resource Saving (HP LaserJet 4 Plus and 5 only)
Resource Saving gives the printer the ability to save certain
entities such as permanent soft fonts, macros, symbol sets and
user-defined graphics patterns when the printer changes
personalities, resolutions or page protect modes. For example, if a
user switches the LaserJet 4 printer from PCL mode to
PostScript mode, all PCL soft fonts macros are lost. The HP
LaserJet 4 Plus/4M Plus printer would not clear these entities
from memory. When the user switches back to PCL from
PostScript all of the PCL entities would still be resident in the
HP LaserJet 4 Plus/4M Plus printer. Resource Saving can only be
accessed when the printer has the PostScript language installed
and a minimum memory configuration of 7 MB. If the printer has
a duplexer option, the minimum amount of memory necessary to
access Resource Saving is 13 MB.
The Resource Saving configuration is located in the Memory
Configuration Menu. Resource Saving can be set for three modes,
AUTO (default), ON, and OFF. Auto configuration sets the
Resource Saving for PCL and Postscript to a minimum value (400
KBytes) for each personality. Setting Resource Saving to ON
allows the user to determine how much printer memory will be
used for Resource Saving for the PCL personality and the
Postscript personality. The memory can be allocated in 100
KBytes increments. For example, if the user sets the Resource
Saving memory size to 200 KBytes, a total of 400 KBytes of
memory will be assigned to Resource Saving. 200 KBytes of
memory will be used for Postscript Resource Saving and 200
KBytes of memory will be used for PCL Resource Saving.
Turning Resource Saving OFF disables the Resource Saving
function and no memory is allocated to Resource Saving.
