/* pbmtolj.c - read a portable bitmap and produce a LaserJet bitmap file
**
** based on pbmtops.c
**
** Michael Haberler HP Vienna mah@hpuviea.uucp
** mcvax!tuvie!mah
** misfeatures:
** no positioning
**
** Bug fix Dec 12, 1988 :
** lines in putbit() reshuffled
** now runs OK on HP-UX 6.0 with X10R4 and HP Laserjet II
** Bo Thide', Swedish Institute of Space Physics, Uppsala <bt@irfu.se>
