Hi, Rob. Make sure you set up printing according to the instructions in
the hpoj documentation. In particular, you can't just print to something
like /dev/lp0 or /dev/usb/lp0, because the low-level I/O driver which
allows you to scan (ptal-mlcd) has to have exclusive direct access to
the device. Instead, you print to something under /var/run/ptal-printd
(for lpd) or using the "ptal" backend (for CUPS).
I hope this helps. If you have any further questions or problems about
the hpoj software that aren't covered in the documentation, the hpoj-devel
mailing list (http://hpoj.sf.net/join.shtml) is the best place to discuss
