The Samba-Bugzilla – Bug 3598
Samba must be restarted to pick up CUPS changes
Last modified: 2006-03-10 16:25:12 UTC
I'm using CUPS 1.1.17 with Samba 3.0.20. After I added a printer using the CUPS GUI, if samba does not get restarted, I will not be able to see the newly added printer in the 'enumprinters' call.
Enclosed is the samba logs (with log level set to 10) and the enumprinters call before and after the printer is added. I also enclosed the CUPS printcap and printers.conf file.

Refer to the 'printcap cache time' parameter in smb.conf.
Also note that a manual sighup will for an immediate
reload of the printer list. If neither suggestion addresses,
the problem then please reopen.
CUPS 1.1.x does _not_ provide any means to notify an application about a change of the configured printers. That was the reason we had to implement this polling feature Jerry referred to by the 'printcap cache time' parameter. At the moment we use 0 which disables the polling at all.
Jerry: This might be a default we should change in future releases. We're using it set to 750 in the default smb.conf for several Samba releases with SuSE Linux and had no problem at all.
In contrast to this we have again and again this 'printer do not appear' complains from customers. I must correct me: We _has_ this complains before the feature was introduced and our default 750 seconds used.
Lars, we've set that default for a while now.
