did you set it up under the cups web config at localhost:631?

Brilliant! The web interface to configure printers told me straight away
that there is a problem with the Serial port (Permissions) - This was easily

Now the printer is printing, but it's printing garbage. I know that when I
cat something to the serial port that it actually works fine (this is when
it is a plain text file) but printing a plain text file seems to print
garbage (no idea where the formatting comes from). I will try the plain text
driver to see if it works. Please let me know if you have any more pointers
for me.
