# To configure this interface script under Solaris LP use the following
# command:
#
#	lpadmin -p printer -v /dev/... -I"postscript,pdf" -Tunknown \
#		-i /usr/sfw/share/ghostscript/interfaces/GSinterface \
#		-o GS_DEVICE=(gs-device-type) \
#		[-o OutputFile=(file/device)] [-o PAPERSIZE=(size)] \
#		[-o RESOLUTION=XxY] [-o banner-type=(ascii|postscript)] \
#		[-o GS_OPTIONS="-sIjsServer=... -sIjsParams=..."]
#
#	see gs(1) for more information about values that can be used for
#	GS_DEVICE, PAPERSIZE, and RESOLUTION, and GS_OPTIONS.
#
#	There is a known problem printing through a /dev/lp? parallel port
#	on a Solaris x86 machine.  If you have selected the correct GS_DEVICE
#	and get garbled output when printing under this configuration, running
#		"lpadmin -p printer -H nopush"
#	should fix the problem.
