[Miguel Gastelum <miguelgastelum@xxxxxxxxx>]

I have three thermal receipt printers connected to Xubuntu 14.04 with
Model Generic / Text only driver when print command three jobs, one for
each printer, sometimes one or two printers stops are left with the job
without printing, and the queue print says that the printer is turned
off or disconnected.

If I send a new print job to the printer that has been standing prints
the job that had been printed and the new, but the new print was
incomplete.

CUPS Version:  cups 1.7.2-0ubuntu1  amd64

Title:
  USB Printer: some times the jobs are printed and some times not

Status in “cups” package in Ubuntu:
  Fix Released

Bug description:
  This is a Samsung ML-1860 laser monochromatic printer, attached at
  usb.

  The problem is: only some pages are printed. Example: I send 6 copies
  of some page to print but only 4 are actually printed. Or some times
  none of them. Rarely all of them are printed. If I disconnect from
  usb, then send the job and reconnect, the chance of get the print done
  is increased.
