I bought a USB to parallel adapter, plugged it in, and it worked GREAT!
Now, 2 weeks later my HP Deskjet 720C quit printing.
Applications seem to put the document into the spooler correctly, but the
spooler errors out.
I have tried deleting and reinstalling the printer, but no luck so far.
 
Did you remove USB support and add it back?

Enable hidden devices in Device Manager to view the printers.

I enabled hidden devices, but the display is exactly the same as before.

I have 12 items listed under USB controllers. None of them tell me which is
which. I have one named "Unknown device", and I think this is the printer.
It used to say "USB Printer" or something like that. I have tried updating
the driver to no avail

As for "remove USB support and add it back" I don't know what you mean.
Could you please give me less cryptic instructions?

Thanks

My computer has NO ports other than USB - no parallel, serial, game, or
anything else. That's why I had to use the USB adapter.

I removed everything I could find relating to printer support and then
plugged into a different USB port. It reinstalled and is working again.

Thanks- but i needed to know about LPT1 - find a couple of questions earlier
but noone seems to get any answers that work AND HP don't care. I've lost my
faith in HP so I will get an USB adapter to solve the problem and later chose
an other supplier. Best Regards NisseO

That's a wonderful printer, one of the best that HP ever produced, but
it goes back a long time. I replaced mine with a HP PS8250 a while
before VISTA came along (it's discontinued now but there are other HP
Vivera 02 ink printers available) and I certainly do not regret it.

Sometimes we do have to bite the bullet -- or not upgrade the OS.
