[Confused]

I am currently printing word docs from canon copier. I have set 2 printer
drivers from printer control setting (one from recycled paper tray and one
from clean paper tray). The problem I am facing now is that even when i
select the printing driver for the recycled paper, the output is printed from
clean paper.

When i asked the Canon help desk, i was told that Canon's printing
preference is typically overwritten by Word printing preference. Is this
true? Does it mean that I have to frequently adjust the Word page set up
(paper source) setting every thing i decide to switch between recycled paper
and clean paper??? This would be really frustrating if it is the case.
