No, currently the driver only understands the listed attributes.
We may, at some future time, define additional ones or allow any
option in the PPD file to map to a PJL command. Patches would be
welcome (submit via "http://www.cups.org/str.php")

GS is not involved with the PJL or PCL generation - the CUPS driver
receives raster data from Ghostscript, the imagetoraster filter,
or any of the cgfootoraster filters that Apple provides.
