Parallel port problem

[awardb]

Hi

New to this forum. Have installed VBox 4.3.12 on Win7 64-bit Host. Installed Windows XP 32-bit as Guest. Have closely followed instructions on Parallel Port printing as outlined in the forums. However, as soon as I attempt to start my WinXP VM *after* enabling the parallel port, the VM crashes with an error message containing some of the following info:

Unable to open session. Could not open file 'ParallelPort0" (VERR_FILE_NOT_FOUND)

I'll post a 2nd message right away, unfortunately, when this happens, it crashes the Host Windows after a few minutes, so I've got to write it down.

Any ideas? This computer has a built-in Parallel Port, on the motherboard.

OK, here is the exact message:

Parallel#0 could not open 'LPT1'
(VERR_FILE_NOT_FOUND)

Parallel device 0 cannot attach to host driver
(VERR_FILE_NOT_FOUND)

Could this be because I don't have the driver software for the LPT printer installed yet? Or something else.

Please help, thanks in advance.

You seem to be thrashing around trying different device names. You only need one device name: the correct one.

As to how you find it; when you look in the Device Manager of the host, Ports (COM and LPT) branch, what name does it show for your host's LPT port?
