Ok, it is consistent and repeatable:
*Everytime* I do a routine 'yum update' on the CentOS 6.5 server (64-bit) the printers (both of them networked laser printers, one an [old] HP Laserjet 4200 and one a [new] Brother MFC-9970CDW), cups loses the ability to print (its filter chain becomes broken). According to the CUPS mailing list, this error is 'never' because of of problem with cups, but always with the 'underlying operating system' -- eg the 'underlying operating system' has messed with the filters CUPS uses for the printers.
I have not experienced any broken chains. With generic (Debian Wheezy) driver my Samsung 1640 printer would not print any pages randomly. cups administration (localhost:631) would show things are fine. At times a cups restart would help.
So is this a *known* problem? Or is there something Redhat has done to the distributed cups RPM (or is it something the CentOS developers have done to the Redhat source rpm)?
I don't think so. My problem with Samsung 1640, were on Debian.
The *appearent* cure (workaround?) is to delete the printers, and re-install them.
Yes, it would work for a while for me.
Has anyone else had this problem?
In my case, I installed the printer driver for 1640 from Samsung's support site and things have more stable for me.
