[cups] Envelope printing problem

[ToddAndMargo]

Hi All,

Help!

$ rpm -qa cups
cups-1.6.3-17.el7_1.1.x86_64

$ uname -r
3.10.0-229.11.1.el7.x86_64

I just upgraded to Scientific Linux (RHEL clone) 7.1.

Now I can't print an envelope to my Oki B4350.  Paper
size mismatch.  CUPS tells my printer that a #10 envelope
(Monarch Envelope) is a B5 piece of paper.  Overriding
the prompt from my printer results in a ruined envelope.

This reproduces from Libre Office and Lotus Approach
and Word Pro running under Wine Staging.

Many thanks,
-T
