+Hi, Zdenek,
+
+you need to be aware, that the Samba print files pass thru 2
+different "spool" directories. Once the incoming directory
+managed by Samba, (set f.e. in the "path = /var/spool/samba"
+directive in the [printers] section of "smb.conf"). Second is
+the spool directory of your UNIX print subsystem. For CUPS it is
+normally "/var/spool/cups/", as set by the cupsd.conf directive
+"RequestRoot /var/spool/cups".
+
+I am not sure, which one of your directories keeps the files.
+ From what you say, it is most likely the Samba part.
+
+For the CUPS part, you may want to consult:
+
+   http://localhost:631/sam.html#PreserveJobFiles and
+   http://localhost:631/sam.html#PreserveJobHistory and
+   http://localhost:631/sam.html#MaxJobs
+
+There are the settings described for your CUPS daemon, which
+could lead to completed job files not being deleted.
+
+"PreserveJobHistory Yes" -- keeps some details of jobs in
+cupsd's mind (well it keeps the "c12345", "c12346" etc. files
+in the CUPS spool directory, which do a similar job as the
+old-fashioned BSD-LPD control files). This is set to "Yes"
+as a default.
+
+"PreserveJobFiles Yes" -- keeps the job files themselves in
+cupsd's mind (well it keeps the "d12345", "d12346" etc. files
+in the CUPS spool directory...). This is set to "No" as the
+CUPS default.
+
+"MaxJobs 500" -- this directive controls the maximum number
+of jobs that are kept in memory. Once the number of jobs
+reaches the limit, the oldest completed job is automatically
+purged from the system to make room for the new one. If all
+of the known jobs are still pending or active then the new
+job will be rejected. Setting the maximum to 0 disables this
+functionality. The default setting is 0.
+
+(There are also additional settings for "MaxJobsPerUser" and
+"MaxJobsPerPrinter"...)
+
+For everything to work as announced, you need to have three
+things:
+
+   * a Samba-smbd which is compiled against "libcups" (Check
+     on Linux by running "ldd `which smbd`")
+
+   * a Samba-smb.conf setting of "printing = cups"
+
+   * another Samba-smb.conf setting of "printcap = cups"
+
+Note, that in this case all other manually set printing-related
+commands (like "print command", "lpq command", "lprm command",
+"lppause command" or "lpresume command") are ignored and they
+should normally have no influence what-so-ever on your printing.
+
+If you want to do things manually, replace the "printing = cups"
+by "printing = bsd". Then your manually set commands may work
+(haven't tested this), and a "print command = lp -d %P %s; rm %s"
+may do what you need.
+
+You forgot to mention the CUPS version you're using. If you did
+set things up as described in the man pages, then the Samba
+spool files should be deleted. Otherwise it may be a bug. On
+the CUPS side, you can control the behaviour as described
+above.
+
+If you have more problems, post the output of these commands:
+
+   grep -v ^# /etc/cups/cupsd.conf | grep -v ^$
+   grep -v ^# /etc/samba/smb.conf | grep -v ^$ | grep -v "^;"
+
+(adapt paths as needed). These commands sanitize the files
+and cut out the empty lines and lines with comments, providing
+the "naked settings" in a compact way.
+
+Cheers,
+Kurt
