Check the printer has an open port 9100. $ nmap 192.168.0.14 Starting Nmap 7.80 ( https://nmap.org ) at 2022-06-30 23:01 BST Nmap scan report for 192.168.0.14 Host is up (0.030s latency).

Send both files directly to the printer with > netcat 192.168.0.14 9100 < ippeve.urf Command seemed to hang or await job completion. Printer printed a good 30-odd pages, either blank or containing a line or two of binary/gibberish. Device job cancel button did not respond. Opened paper tray, pressed cancel button, job stopped. Re-inserted tray, job continued. Opened tray, cancelled job, ^C to stop netcat, power cycled printer, order restored. > netcat 192.168.0.14 9100 < drvless.urf Same, though this time I stopped it after a few pages Thanks, Gareth
