Can you add the printer with the web interface of CUPS? Go to http://localhost:631/ and click on "Administration". If your printer or at least the first parallel port is shown, click on the appropriate "Add this printer" button and choose the model on the next screens. When asked for user name and password, enter your user name and your password.
If your printer/the parallel port does not appear, click "Add Printer" at the top of the page and fill in the fields on the following screens. In the "Device" step choose "LPT #1", in the following steps chose your printer model. Does this work? -- since updating to edgy, HP Deskjet 600 is not detected at all https://launchpad.net/bugs/59934 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
