Package: samba Version: 2:4.5.12+dfsg-2+deb9u2 Severity: normal File: /usr/sbin/smbd
Dear Maintainer,
Printing from Win8/Win10 clients to a printer shared on a samba server
using printing=bsd does not work (printing from smbclient and WinXP/Win7
clients is OK).
The file to print is transferred to the spool directory, but
find_printer_index_by_hnd() fails with a "printer handle not found:
invalid handle" error, and printing is cancelled.
I made the following change to try to find out what's the problem
with the handle:

- dump_data(4, (const uint8_t *)hnd, sizeof(*hnd));
+ if (count==0)
+ DEBUG(4,("Policy list empty.\n"));
+ else {
+ DEBUG(4,("Policy not found: "));
+ dump_data(4, (const uint8_t *)hnd, sizeof(*hnd));
+ }
p->fault_state = DCERPC_FAULT_CONTEXT_MISMATCH;
With this change, the smbd log (level 10, attached) shows that the handle
isn't found because the policy list is empty.
Here is my smb.conf:

Although printing is cancelled, and lpr isn't called by samba, the
spooled file is not deleted, so I could work around the problem by
watching the spool directory with an inotify-based tool, and calling
lpr from there, but it would be nice to fix this in samba.
If you need more details, feel free to ask.
