Thanks for doing that.

Pass on this for the moment. My understanding is that there is no
difference in what lp and lpr do.

The error_log shows that two-sided-long-edge is sent to the printing
system. See argv[5]. It should then be sent on to the printer. The
printer supports two-sided-long-edge.

But we have

   [Job 238] Unable to do two-sided printing, setting sides to \'one-sided\'.

Now, where is that coming from and why? Investigating.

Rick, you can help with more information. Please give what you get for

  avahi-browse -rt _ipp._tcp
  driverless
  lpoptions -p PRINT_QUEUE_NAME -l

avahi-browse is in the avahi-utils package.

Cheers,

Brian.
