I wrote a simple filter to print to an nt print queue through
the smbclinet. It tests to see if the file is postscript or
text, and if it is text it sends a control code to tell the
printer to do the lf->crlf conversion.
My problem is that the '\' escapes in the first line get clobbered.
for example, if I print this printcap:
**** begin printcap ****
lp:\
:sh:\
:lp=/dev/lpt0:\
:sd=/var/spool/output/lpd/lp:\
:lf=/var/log/lpd/lpd.log:
lplaser:\
:sh:\
:lp=/dev/null:\
:if=/root/filters/smb-filter:\
:sd=/var/spool/output/lpd/lplaser:\
:lf=/var/log/lpd/lpd.log:
**** end printap ****
the entire entry for "lp" will be on one line, but the "lplaser"
entry will print out like it is supposed to.
I know why it is doing it, however I don't know how to fix it. Any
help will be appreciated (script is below).
Thanks,
James
