Subject: smb printer trouble
Sender: owner-freebsd-hackers@FreeBSD.ORG
Precedence: bulk
X-Loop: FreeBSD.ORG

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
