Pass on this for the moment. My understanding is that there is no difference in what lp and lpr do. > I then ran: > lpr -o sides=two-sided-long-edge lipsum.txt.pdf > > It printed one-sided. > > This used to work correctly, then a few months ago, it stopped working.

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.
