You can set up your /etc/printcap to handle this with no problem.
Here is the guts of ours. We have three entries for the HP. One
for 7-bit portrait mode printing, one for 7-bit landscape mode,and
one for 8-bit portrait mode. The filters referenced set the line
spacing to give us 66 lines/pages and set landscape/portrait.
We have 7 & 8 bit entries because the eight bit mode requires
LF & CR for each line whereas 7-bit does not. So we only use
8-bit for ditroff and other graphic material. The printcap:

lp|ap|arpa|ucbarpa|Serial printer:\
	:br#9600:fs#06320:tr=\f:of=/usr/lib/lpf:lf=/usr/adm/lpd-errs:\
	:lp=/dev/ttyhd:

	:br#9600:lp=/dev/laser:fs#00320:\

	:sd=/usr/spool/type:\
	:of=/usr/local/fport:

laser is 7-bit portrait
waser is 7-bit landscape
type is 8-bit.

Good Luck!
