RESOLUTION Print resolution in dots per inch. When a
job is sent, if there is not enough
memory to run with the current

overrides the resolution and/or
page-protect values to run the job.
When the resolution is changed,
memory is reconfigured and all
downloaded fonts, PCL macros, and
PostScript dictionaries are lost
(however, no I/O data is lost). Refer to
“Commands that Affect Printer Memory”
