The `hpljii` terminal driver supports the HP Laserjet Series II printer. The `hpdj` driver supports the HP DeskJet 500 printer. These drivers allow a choice of resolutions.
Syntax:
set terminal hpljii | hpdj {<res>}
where `res` may be 75, 100, 150 or 300 dots per inch; the default is 75. Rasterization at the higher resolutions may require a large amount of memory.
The `hp500c` terminal is similar to `hpdj`; `hp500c` additionally supports color and compression."
