HPijs
HPijs is a monalithic printer driver supplied by HP. It allows 99% of all the HP printers to be 'driven' correctly when printing groff forms.
The default in the system is 'HP LaserJet'
If you have a different printer model then you can specify this using
HPijs_{Printer-Letter} e.g.
if you have a HP 1050 connected as printer B then
use the entry:
HPijs_B = HP LaserJet 1050
would cause the jobs to be passed off to HPijs using the correct model.
Note: If you have a Colour Laserjet (HP 4600, 5500 etc.) then set the model to 'HP Color LaserJet 5500'.
For a list of model names you can use see: http://hpinkjet.sourceforge.net/printmodedescr.php
