CentOS - Aug 2014 - CentOS 6.5 printer weirdness...

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.

how are you installing/configuring the printers?  are you editing any 
.conf files that are included in the packages ?

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.

I don't think so.  My problem with Samsung 1640, were on Debian.

Yes, it would work for a while for me.

In my case, I installed the printer driver for 1640 from Samsung's
support site and things have more stable for me.
