Saving Downloaded Resources With Context Saving
Saving Downloaded Resources With
Context Saving
The context saving feature determines how memory is allocated to deal with resources
and data retained in memory from a previous job. This data may be needed again to
process another print job.
During a PCL print job, the memory stores the PCL personality and receives and
processes data for print jobs from the host computer. In order to process the print job,
the memory must also hold and manage downloaded resources (soft fonts, symbol
sets, macros, etc.). With only the PCL personality installed, the printer can use all
available memory to hold and manage downloaded resources.
However, if you install the optional A-32 module for Adobe PostScript 3, the printer
memory must then allocate a portion of memory for the printer’s two personalities—
PCL and Adobe PostScript. Normally, when the printer has to switch personalities, it
has to delete the downloaded resources for the current personality before it can start
the new print job with the new personality. With this context saving feature, you have
the option of keeping all downloaded resources in memory for both personalities, even
when the other personality is not currently being used to process a print job.
Keep these important points in mind about the context saving feature:
■
Even after the PostScript option (A-32 module ) is installed, context saving will only
become available after at least 8 MB of extra memory has been installed.
■
Context saving is not only useful for switching between PCL and PostScript. If the
printer is using the PCL personality and the PDL is switched up to PCL6, any fonts,
macros, etc. downloaded under PCL5e will be deleted. To protect these resources,
context saving is necessary.
■
You can turn context saving on for one or both of the printer personalities. Memory
space for either personality cannot be allocated from the printer control panel; the
printer does this for you automatically.
