Thanks, nice to know it still works ... :)

I have not received any reports of anybody who tried it.
I own a HP3300 (which has no parallel port connection) myself so
I have also not tested it myself.

When I wrote the ieee1284 support, I used the very first version of
it (0.0.0) and it compiled OK. It is very possible that the
interface of libieee1284 has changed since version 0.0.0 .
The biggest difference seems to be the 'flags' parameter.

If you would like to look into this, you're welcome ofcourse.
