I try to print with a receipt printer. It all worked fine but I was sending prints to quick to the device.
Now I get the error:
usr/bin/lpr: Too many active jobs
I would like to clear all active jobs. I tried rebooting and turning the device on and off, but it does not help.
The complete error is:
RuntimeException: javax.print.PrintException: java.io.IOException: error=1 running: '/usr/bin/lpr' '-PEPSON_TM_T88V' '-J Java Printing' '-o media=Letter' '/var/folders/fb/fnzlgb7d2p7_h4gspnvdldzr0000gn/T/javaprint159865029725996489' /usr/bin/lpr: Too many active jobs. Is there any way to clear the current jobs?
lpr has the following options:
