Excel 2010 paper size issue with PCL6 drivers after KB2592687 installed on client

Question

When I connect to the RDS server and open Excel with the PCL6 printer and select File / Print the paper size says Custom Paper Size and I can not change the paper size here, in the Page Layout tab or in the drivers properties pages. Using the PS driver there
is no issue. I've tried using several stock PCL6 drivers from Windows 7 and have the same issue such as the HP LaserJet P4014/4015 PCL6. Using the Lanier LP131n PCL6 or PS I had the issue with PS as well.
I do not have the drivers loaded on the server so it is using Remote Desktop Easy Print. If I do load the drivers and allow it to use them then there is no issue but I cannot configure the printers options without taking ownership of the printer so that
is not desirable.
If I do not install KB2592687 then there is no issue, but that is not an option as I am dealing with a customer who's IT manager refuses to remove this, even to test it, and says our printer driver has the issue and is not compliant with MS TS. 
Could I be missing any configuration, hotfix, policy that could explain this issue or any other workaround? Or is there a change required to our printer driver for this?
Test setup:
I created a new Windows Server 2008 R2 Standard server with SP1, Added the RDS Role, Installed Office 2010 Professional with SP1 using the Terminal Services product key. No updates were installed. I have tested installing every possible update as well for
both Server and Office.
I then created a new Windows 7 Professional x86 with SP1 client, installed PCL6 & PS printers, installed KB2574819 and KB2592687. No other updates were installed. I have tested installing every possible update as well.

Hi,
Did you find any particular Event ID for your issue?
To troubleshoot this issue, have you tried changing the default printer and printing from other programs such as Word or any other?
The issue which you are facing might occurs because the Microsoft XPS Document Converter (MXDC) determines the paper size by using the FormID value on the server. As you commented that you are using Easy print driver first you can find incorrect paper size
if RD Easy Print printer driver first is enabled. 
To work around this issue, use the forms that are defined by the system when you print. The paper sizes for these forms match on the server and on the client computer. Additionally, a printer driver can rename these forms. Please refer below article for more
information.
The client printer may print the documents by using an incorrect paper size if the "Use Remote Desktop Easy Print printer driver first" policy is enabled
Apart from this providing link to understand RD Easy print in Windows 7 & Server 2008 R2.
Hope it helps!
Thanks.
