Missing features in T920 driver

[Anonymous]

We have HP DesignJet T920 in our office and it is working fine for more than a year. Suddenly, I am not able to print on this plotter. 

I have downloaded the latest driver version from HP website and it is working fine except some missing features in the paper size as you can see in the below.

This is before installing the new driver. 

This screenshot from the new driver.

Also, when i print A2 size it prints A3 instead which is really weird !!!???

Have you jumped into the driver's Printing Preferences yet to see if you have scaling overrides in place (Layout/Output Tab)?
Have you explored the issue at HP's Support forums yet? I suspect the issue is with all of your applications, isn't it?
