Using Samba v1.9.18p3 on a Linux system, I find that that any print jobs
sent to a shared printer results in doubled files. It's not that 2 copies
of the print job are actually *printed*, it's just a matter of dual
spool files being created.
For example, the content of the /var/spool/lpd/lj4m directory:
-rw-rw---- 1 bin lp 127 Mar 15 17:48 cfA315Aa10463
-rw-rw---- 1 root root 0 Mar 15 17:48 cfA315Aa10464
-rw-rw---- 1 steve lp 1417816 Mar 15 17:48 dfA315Aa10463
-rw-rw-r-- 1 root root 1417816 Mar 15 17:48 dfA315Aa10464
-rwxr-xr-x 1 root root 9289 Dec 16 10:31 filter
-rwxr-xr-x 1 root root 191 Dec 16 10:31 general.cfg
-rw-r--r-- 1 root root 20 Mar 15 17:48 lock
-rwxr-xr-x 1 root root 342 Dec 16 10:31 postscript.cfg
-rw-rw-r-- 1 root root 29 Mar 15 17:48 status
-rwxr-xr-x 1 root root 146 Dec 16 10:31 textonly.cfg
The 1.4MB print job above was created by me (user "steve"). So why is
there a duplicate file owned by root?
My Samba printer type is undefined (so it's BSD by default), and my
[Printers] section of smb.conf looks like this:
[printers]
comment = All Printers
browseable = No
path = /var/spool/samba
create mask = 0700
guest ok = Yes
print ok = Yes
For small, text-only print jobs, I don't much care that duplicate spool
files are created. The problem is that we routinely print large (10+
megabyte) files, causing a lot of unnessessary server activity and disk
space usage.
Anyone have a clue what's going on here? Thanks.

For example, if you are using "/usr/ucb/lpr -P %p %s; rm %s" as the print command, samba effectively does a "cat $FILE | $LPRCOMMAND" The dual spooling is normal. If you wish to send the job directly to the printer, you will have to use some sort of LPR client on the Windows box and bypass samba. PS : Check the man pages on "lpr command" and others (ie. lprm, lpq, etc... ) for more info and use testparm to see what value for the commands is currently set.

[snip] Assuming that's correct (and I strongly suspect it is), and assuming you're using the lpr (as opposed to lp) command, try "/usr/ucb/lpr -s -P%p %s; rm %s" This will avoid the spooler making a second copy. You can also try the lp command (System V), as it tries not to take copies unless you say ``-c''. --dave (too many assumptions! take some out!) c-b -- David Collier-Brown, | Always do right.
