Usually depends on the application and not the driver.
Since I have never seen Nuance PDF I can't recommend the proper settings application side.
Acrobat/Reader can do it with a simple check box.
For MS Office products it is in Page Setup (Do not use the top option, which is normally the default) The one currently blue in the screenshot its what you want
I am looking to set my default printing with the Xerox 7855 to automatically select to whatever the doucment size is. We have trays for legal, two different types of letter and Tabloid.
If I have a legal sized document I have to specify exactly what paper type to use, rather than it just printing from the drawer that has legal paper and the same with Tabloid sized paper.
I tested a couple different printing options out with a document that has pages that are letter, legal and tabloid sized and it just kept going to the letter size as a default.
The application I am printing from is Nuance PDF Professional 7.3
The changes I made included changing mixed output size, chaning scaling options, chaging mixed size originals.
If you have a solution please share.
