[Samba] Cups printer shared via samba require drives to be mapped

[Melinda Taylor]

Hello,

I am sharing my cups printers via samba (2.2.7) on a redhat 7.3 machine 
running a firewall configured with iptables.

I have included my smb.conf file below. My problem is that windows machines 
can setup the printer just fine, search for the
the server astro, the users enter their smb passwd and username and they 
can ste up the printer.

However I find everytime they reboot their machine, they can no longer 
print to the printer. It is still there but print jobs just sit there. If 
the user, accesses a shared drive such as /home or /data. They are able to 
print again after clearing the print queue. I have got around this problem 
temporarily by mapping a network drive from the server astro on the windows 
machines however sometimes, windows for some unknown loses this mapped 
drive (even though I have set reconnect at logon).

Does this seem like normal behaviour? Is there someway to get around having 
to map a network drive to get the printer to work?

Thanks,

melinda
