Applications over-ride drivers, that can't be changed.
Luckily, MS Office tends to at least hold onto your last used settings, annoyingly, they use weird terminology.
So when you go into Layout > Page setup > Paper and you see it is on Default tray (Automatically select) you assume that means it will automatically select the right tray, but you would be wrong, it will simply select what ever the default tray is as set on the printer itself. If you try it on Automatically Select it will usually work properly and will print to a printer using whatever page size the document is, and the tray it is loaded in. I have honestly had much better luck with this using the Native Xerox print drivers than I have had with printers that were using the Global Print driver.
But you really have no hope if the document is Letter size and you want it on Legal/Tabloid, something will need to be told exactly how to resize it in MS Office, it doesn't have resize features like Adobe products tend to
I've configured one tray for legal paper and another tray for tabloid paper.
On my computer I've setup a legal-size preset to use the proper tray, and ditto for a tabloid-specific preset.
They don't work :(. I have setup a test legal-size and tabloid-size documents in Microsoft Word. When I print, the photocopier has an error message requesting 'additional resources.' When I check the print job in the queue, the printer is asking for 8.5" x 11" size paper in the legal or tabloid tray.
What I discovered is two workarounds:
1) My default printer is a small HP desktop printer beside my computer that only does letter-size paper. In my application (e.g. Word) the 'Page Setup' is configured to letter-size and the HP printer. If I change the setting to the Xerox 7855 and legal/tabloid, then the print job will go through.
2) In the print menu > Paper Handling > turn on 'Scale to fit paper size' and change the destination size to legal/tabloid.
As you may imagine, neither workaround is convenient for the average user in our office.
Is there any simplier way to print legal/tabloid-sized documents? just let me know?????
