Just a thought as I have not been following the thread - why not use a |
50 |
network printer? If its gentoo in a virtualbox on a windows machine you |
51 |
can share the windows printer and use cups on the linux side to redirect |
52 |
to it via samba. No need to worry about parallel ports or physical |
53 |
printer connections in the vm, and the original host can continue to use |
54 |
the printer on the parallel port. |

Apologies if its already been mentioned. |
