You want either an input filter to add CR's, or some method of telling
the printer that lines end with only NL, not CR NL. For example, here
is my input filter for HP deskjet 890:
(if you just want to print postscript files, install the ghostscript
package, and check 'gs -?' for a cannon driver that resembles the printer
you have).
#!/bin/sh
#
# if-djet890: a filter to print plain files or postscript files
#
DPI=600
# Change this to your desired initialization string for the printer
# mode you want. This does (for HP 800 series):
# ESC & k 2 G : CR->CR, LF->CR+LF, FF->CR+FF
# ESC & s 0 C : Turn on line wrap.
# ESC & l 0 O : Portrait orientation.
# ESC & l 2 A : US Letter sized paper.
# ESC ( s 0 P : Fixed width characters.
# ESC ( s 3 T : Courier typeface.
printf "\033&k2G\033&s0C\033&l0O\033&l2A\033(s0P\033(s3T"
read first_line
first_two_chars=`expr "$first_line" : '\(..\)'`
first_six_chars=`expr "$first_line" : '\(......\)'`
if [ "$first_two_chars" = "%!" ]; then
(echo $first_line && cat && printf "\f") | \
/usr/local/bin/gs -r$DPI -dSAFER -dNOPAUSE -q -sDEVICE=cdj850 \
-sOutputFile=- - && \
exit 0
elif [ "$first_six_chars" = "x T ps" ]; then
(echo $first_line && cat && printf "\f") | \
/usr/bin/grops | \
/usr/local/bin/gs -r$DPI -dSAFER -dNOPAUSE -q -sDEVICE=cdj850 \
-sOutputFile=- - && \
exit 0
else
(echo $first_line && cat && printf "\f") && \
exit 0
fi
exit 2
# END
/etc/printcap should look something like:
lp:HP DeskJet 890C:\
:sh:\
:sd=/var/spool/lpd/djet890:\
:lp=/dev/lpt0:\
:lf=/var/log/djet890.log:\
:if=/usr/local/libexec/lp/if-djet890:
This will take plain text (perhaps binary files, haven't tried), postscript,
and 'zcat /usr/share/man/man5/printcap.5.gz | eqn | tbl | pic | troff -man |
lpr' type lines.

Real Programs don't use shared text. Otherwise, how can they use
functions for scratch space after they are finished calling them?
