LPT1 printer..is it possible?

Host XP SP3...Guests VISTA Ultimate & WIN95

I have a Canon LBP-810 Laser printer installed on the host using
parallel (LPT1) connection and working normally under XP.

I am trying to configure the same printer on the above two guests but
both give the same problem.

I have installed the correct drivers for each guest and both are
correctly recognised and installed and reported correctly in the list of
printers.
Unfortunately neither will print a test page nor anything else come to
that.
I have received a message: "Printer not responding" or "Incorrect
printer" or just nothing.
I have tried changing every option I can find...RAW/EMF...Share/Not
share...local/network...Direct/Spool...timeout time...etc..etc. but to
no avail.

The VPC Settings are correct too, with LPT1 enabled.

Is this something I should be able to do?

Any feedback gratefully received.
regards

I would suspect this since you have installed that printer on the
host, which means that the host is monitoring the printer port. That
would make it unavailable to the guests.

I have found that the only way to use the LPT ports in guests is to
*disable* the print spooler on the host....

Another thing, you talk about two guests being configured for use ofd
the LPT1 port. THis is not possible (at least if they are to run
simultaneously) because there is no sharing mechanism in VPC2007. THe
hardware is assigned a guest on an exclusive basis.

I would try to install the printer on the guests as network printers
instead and share it from the host. In that scenario you would not
assign the LPT port to any guest and you would keep the print spooler
running on the host.
Do it just like you would if you had one PC on the network with a
printer and the other PC:s sharing that via the network. Generally the
best idea.

Thanks BO, good advice that makes sense.
I have attempted your approach and cannot get any of my guests to see
the host's shared printer. I accept that this is probably my shortcoming
in setting up a network and I shall just have to battle on.
Thanks again for your input
