Print multiple copies from different trays.

I have an HP 4050TN that i would like to print multiple copies of
single page documents from multiple trays. I have tried setting the
preferences on the printer, at the aplication (word 2003 & quickbooks)
and on the computer. I have not found the right combination of
settings to make this happen. Ultimately what i would like to have
happen is that when i send the document to the printer i want it to
print from tray 3, which has preprinted forms in it, and the manual
feed so i have a hard copy of the order. where is my problem coming
in? any help would be appreciated.
