known Problems with BeagleBone

  • Printer does not power on: Wait, the script checks for print-jobs only every 30s. Also, some morronwell-meaning-person might have disconnected the BeagleBone, the Printer or the power or switched off the printer manually.
  • Does not print but printer powers on. (Printers displays “STANDBY” not “PROCESSING”): Check if green LEDs on Belkin USB-Hub are lit. If not, unplug USB-Hub from BeagleBone, unplug USB-Hub-Power and plug everything back in.
  • If it does not work: Check if the tiny white usb-hub has power. Disconnect and Reconnect all USB-cables and power from the tiny white usb-hub. That should be all that's needed, unless the USB-LPT cable has a loose contact inside the cable.
  • Printing slow: recently we switched the Laserjet from PCL driver (fast) back to PostScript-Driver (slow) since only the PostScript-Driver supports A3.
  • Injket Error page: The CUPS support for the 2250TN is poor. Currently there is a choice between one driver that crashes the printer after one page or another driver that prints successfully but with one error-page after each print-job. We choose the later.
  • It's printing garbage: Use the correct autodiscovered CUPS printer. Don't configure something yourself.
  • on a recent test, a 32 page paper printed, though on some pages only 66.6% text was printed. We assume it was the devils work, as no other possible reason or log entry came forth and plead guilty

Trouble shooting

In the unlikely case that the printer does only print PS or PCL commands, abort the print job directly on the printer or you might end up with hundreds of useless pages.
