# printfax <filenames>
#
# print a standard "g3" file (in high resolution).
# Needs: the pbmplus package, and the pbmtodot utility with my patches (to
# be able to print 360x180 dpi)
#
for file
do
#
# the resolution is encoded in the name of the fax: "fn*" vs. "ff*"
#
if expr "`basename $file`" : "fn" >/dev/null
then
# normal resolution
yscale=1.84
else
# fine resolution
yscale=0.92
fi
#
# Modify this for your needs
# (Don't forget to adapt the scaling - fax resolution is 204x196 dpi)

# Sample for PostScript-printers:

# Sample for a HP laserjet, using GhostScript
