Comment 81 for bug 872483

#56: This worked for me. I'm using ubuntu 16.04.5 LTS with CUPS 2.1.3. Printer: Zebra ZD-510HC firmware V83.20.18Z.zip (released 1-Aug-2019). My problem was that it printed one job, then next ones appeared to be received by the printer (LEDs flashed) but nothing was printed.

Thank you so much! I hope this page stays where it is and can help others. I had invested many hours over the course of the last 2 weeks trying to fix this problem and your solution finally fixed it.
