setresolution
setresolution —
integer
changes the resolution for the current print job and discards unprinted data.
Refer to your printer user documentation for a list of supported resolutions. The
following integers are valid:
300 dpi is set to On
300
600 dpi is set to On
600
1200 dpi is set to On
1200
Notes:
• For some printers, the resolution value returns to the user default setting for
the
Print Resolution
• The printer waits for the paper path to clear before changing the resolution.
• If the resolution is changed for the back side of a duplexed sheet, the printer
ejects a blank back page, changes the resolution, and prints the information
for the page where the resolution was changed on the front side of the next
sheet.
This operator is equivalent to executing the following PostScript emulation
sequence:
<< /HWResolution [xres yres] >> setpagedevice
where = .
xres yres
