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?
