NW 6.5 SP5, created iPrint printer for HPLJ8000 and HPLJ8150 and loaded the
XP & W2K drivers. However, when try to print, I don't have the option to
pick the tray source as "manual feed". Source is set as "auto select" and
it is grey out so I cannot change it to manual feed.

If I add the printer using the old queue based way and use the as printer
driver then I get the option to use "manual feed".

So on my workstation after I installed the iPrint printer, I manually
update the printer driver and still do get the "manual feed" option.

Anyone has any suggestions?
