In print manager/properties/setup define the form tray/name.
In print manager/properties/details there is a checkbox called
"hold
mismatched jobs" check it.
Now when you go into a program (like notepad) and print you just
select the
correct form. If it's not the current one in the printer the job
is held in
print manager. I'm not sure if you get notified if the wrong form
is in the
printer, but you can check print manager to see if it's printing.
