[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.

This is used in a restaurant so that these errors can not happen.

And I hope you can help me with this problem.

Title:
  usb printer works intermittently after upgrade to Precise

Status in “cups” package in Ubuntu:
  Fix Released

Bug description:
  I have a Canon MF4150 mono laser printer...was in use on Oneric with
  no problems.  Testing Precise (12.04) on another machine before
  cutting over & found printing problems with this printer.  Tried to
  research the issue but have not found a fix.

  When first powered up, the printer works fine initially.  After a few
  jobs, it stops working.  It appears that after the last successful
  job, the printer is left in a hung state...visible evidence is the
  "Processing Data" indicator on the printer remains on...forever.  In
  normal operation, this indicator goes off immediately after the last
  page of the job is completed.  Once in thsi state, the printer never
  prints again until power is cycled.

  However, while in this state, Cups still appears to send print jobs,
  but nothing actually prints.  The cups log indicates that cups is
  sending data to the printer in a sequence of transfers (8192 bytes
  each).  So cups apparently thinks the printer is accepting the job.
  I've compared the log sequence for jobs that print and jobs that don't
  and I can find no difference in the information reported in the cups
  log (at full debug level logging).

  The problem is unlikely to be related to drivers since the printer is
  operating in raw mode (the machine is a samba server for Windows
  printing clients).

  Have tried uni-directional constraint suggested in various places.
  This printer does not work at all if this option is applied.

  I have tried blacklisting the usblp module.  This does not solver the
  problem.

  Since it does not happen every time, it seems related to the sequence
  or timing of usb transactions.  Were there significant changes in usb
  behavior that would have affected raw printer handling between Oneric
  and Precise?

  Need to move forward from Oneric...printer testing is my last issue.
  Help would be greatly appreciated.
