Hi,

It seems that you are running in a speed problem. By default the SYSV 
lp-spooler is using a reference to the position of the printfile. If the 
printfile is send via a network normally the file is created only 
temporarily. This means it is automatically removed after receiving the 
signal from the spooler that the file has been queued.

Due to this circumstance the default print command under Samba is "lp -c 
-d%p %s; rm %s". This means that the spooler copies the file to its spool 
directory instead of using a reference. The rm command is just to make sure 
that the Samba spooling area is really cleaned off.

I do not know why you could print before without a problem, but I believe 
if you extend your command with the "-c" and the ";rm %s"
your problem will
be solved.

HTH,
