The printer is"HP LaserJet Plus Pro M148fdw", connected by ethernet.I first created a .txt file, then converted it to a .ps file, then converted to a .pdf file. I then ran the following commands:
lpr -o sides=two-sided-long-edge lipsum.txt.ps lp -o sides=two-sided-long-edge lipsum.txt.ps lpr -o sides=two-sided-long-edge lipsum.txt.pdf lp -o sides=two-sided-long-edge lipsum.txt.pdf All printed one-sided. Then, as root, I ran the command cupsctl --debug-logging Then as regular user, I ran: lp -o sides=two-sided-long-edge lipsum.txt.pdf After many seconds, error reported: lp: Error - scheduler not responding. No output to the printer. 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. I had hoped it would have been corrected, but now I am reporting it.
Please let me know if I can help in any other way. Thank you! Rick On 2022-03-27 08:08, Brian Potkin wrote:

"lpr -o sides=two-sided-long-edge test.pdf" "lpr -o sides=one-sided test.pdf" And same for lp.Thank you for your report, Rick. What is the printer make and model? The situation is that neither command gives double-sided printing?Printing from Okular works correctly as expected.There is a slight difference between your lp command and what Okular does. Okular sends a PostScript file to the ptinter. Not that I can see why that should make any difference, but printing from Evince or Firefox sens a PDF. You could try that. Anyway, let's have a log. Enable debug logging with cupsctl --debug-logging Empty error_log with >/var/log/cups/error_log Print and send error_log as an attachment after compressing it. Regards, Brian.
