Tried setting permission to 777 on /dev/lp0, then no error message appears in the web interface, but no printing is taking place... Helge On 1/19/07, Joe Gilmour <jgilmour@bigpond.net.au> wrote:

Funny, I thought it may have been needed for the user to be a member of group lp but on my working system I'm not. Also in the cups admin page printing test pages is done by root so they should work if it's a permissions issue.
If I recall I did have some problems with an older version of cups but that was with networked printers I think. I think I also played with the BIOS setting for the parallel port settings.
For me though once I actually got my port showing up it just worked.
HTH,
