Vista x64 can't print to vista 32 machine

This is a duplicate - also posted on the Print / fax newsgroup. Help anyone?
--------
On my home network I have a main computer with 2 printers attached, and
shared. I can connect and print from another Vista X86 computer and from an
XP x86 machine. The network configuration is all correct and working well,
except for this one printer glitch.

I just built a new computer with Vista X64, and am stymied by my HP Laserjet
P3005. I cannot get it connected over the network, as I have with other
printers. This is especially strange as I have connected my Canon color
printer without any trouble.

- Canon Pixma on USB, shared - set up without any trouble on Vista 64
computer over the network
- HP Laserjet P3005 on LPT1 - cannot set up.

Downloaded drivers. During the initial setup on the network 64bit machine it
asked for drivers. I had downloaded them and unzipped them, so I pointed it
to the folder, and it appeared to install them. After a pause, I got an
error message from Vista: "Windows cannot connect to the printer. Operation
could not be completed (error 0x0000007e).

I then went to the 32 bit computer, opened the shared properties, and
selected the "additional drivers" button. I re-unzipped the driver locally,
then added the 64bit drivers. No change.

After reading on line, I attempted to create a local port with the //network
name/printer name format. I get "Access is Denied"

Next, I moved the new computer close to the printer and plugged the printer
directly into the 64 bit computer via USB. The printer installed correctly,
with no errors. This tells me that the printer drivers themselves are OK.
So I then tried to create a new local port from within the newly installed
printer properties window - no good, access denied.

I then re-tried to add the printer, hoping that the drivers would be
straightened out by the local install, but no good.

So . . .

Any suggestions??
