I just recently went through some linux printer woes. When my toner cartridge got down below 25% documents spooled from my Linux machine would fail with an out of toner error. Files from windows and the diagnostic pages from the printer itself printed just fine. Turned out I had been using a slightly incorrect print driver on my Linux machine this entire time. After a TON of digging I managed to find the correct driver and was able to print again. Only wasted most of a morning figuring it out. Lol!
Ay, isn’t that the chocolate rain guy??
