My pdf fles usualy print as (binary ??) garbage.

On your WiFi connection, get the outputs of

avahi-browse -rt _ipp._tcp

and

avahi-browse -rt _uscan._tcp

Cheers,

Brian.

The output of the command 'driverless' would also be useful.

Dear Brian,
      Thanks very much for your offer to help me. Unfortunately, I'm
somewhat of a novice on computers, so I don't understand how to carry
out your requests. I don't understand where to go to try to use the
avahi-browse commands, if that is what they are, to get any output.
      Also, I don't understand how or where to use your followup
request concerning "driverless". When I use "driverless" as a command
on a terminal, it produces mo obvious output, but man driverless does
produce the driverless manual, so I guess I do have the command in my
system. So where should I look for its output?
      I await your suggestions/instructions.

       Best regards,
       Jess Weil

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Dear Sir,
      I request that you keep this question of mine open. I have been
extremely busy, but hope to comply with the requests of Brian_p for
more information in the next few days. It is still a problem that I
need to solve.
      Please confirm if it can be kept open.
      Thank you.

Dear Brian,
          Here is the output I got from the three commands you asked me to run. I hope you can reopen the question, and continue to work on it.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Dear Sir,
      On June 7 you sent a similar message to the one shown below,
saying that my question was canceled. I responded on June 9 with a
request to keep the questiopnopen, and then again on June 9/10 with
some additional diagnostic information taht Brian P had requested. I
received two replies from Launchpad on June 10 saying that the request
to keep the question open was receved and taht the additional
information was received.
      Since then I've been patiently waiting to hear again from Brian P
or someone else whether the diagnostic information I sent was
useful, and whether other information was needed from me.
      I still have this problem, and request that the Question remain
open, and that someone contact me about whether it can be solved or
if more information is needed from me.

      Sincerely
      Jesse Weil

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Dear Sir,
      I am sorry to hear that my status has moved from Open to Expired
again. I am still waiting to have a reply from your staff concerning
the new information I sent on June 9/10.
      HOwever, in the meantime the original problem with printing of
pdf files has disappeared. But another problem still remains. So maybe
my case should be renamed " Can't print .doc or .xls files at all".
      I can now print pdf files every time I try. But I can never print
a .doc or a .xls file at all. Would you please refer this to
your experts and ask them what further information they need to try to
help with this.
      Thanks for any help you can offer.

       Sincerely,
       Jesse Weil
