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.
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 noticed that the update I just did included an updated cups RPM.
The *appearent* cure (workaround?) is to delete the printers, and re-install them.
Has anyone else had this problem?
Not me.
I have two Brother printers at home, both networked, and my personal workstation at home is Centos s6.5 64-bit. I've never seen that problem with either printer, one of which uses the drivers shipped with Centos, the other uses Brother's official drivers.
