Is the latest iPrint for Vista (5.04) when coupled with the latest backend
update (iprntnw65sp7b) now support the HP Universal Driver Postscript 4.5?

I'm trying to setup a new HP 4015 printer, and iManager was able to upload
the UPD driver with no reported errors. I was then able to assign the driver
to an established printer.

It looks like UPD knows what model it is, and I'm able to print, and I'm
seeing the HP popups for "replace toner" and such.

So, it all looks to be functioning, but I wanted to make sure that this is
indeed supported.
