Finally, we thank you for your bug report, however, there is little that the Ubuntu developers can do about this, you should directly write to HP. From the HPLIP FAQ (http://hplip.sourceforge.net/faqs.html):
Question: How do I report a bug (defect) or request a feature?
Answer: You may post bug reports or feature requests to one of the mailing lists, or send an email to <email address hidden>.
Richard, you may also look the output when using the option -ldebug as in:
$ hp-makeuri -ldebug
Also, you may check that your printer is supported (and how well) by HP in http:// hplip.sourcefor ge.net/ supported_ devices/ index.html (Yes! Unfortunately, HP sells printers without proper drivers! Sad but true!)
