Description of problem:
I created a print queue via the gui print configuration tool. The queue is of
type JetDirect, i.e., rawprint port 9100. When I use lpr to send a print job
that has back channel data to this print queue, linux will immediately abort the
network connection when the back channel data is sent to it.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.lpr a postscript job with back channel to a JetDirect print queue.
2.If the back channel occurs early, not all of the pages will print because
linux drops the connection.
Actual Results: For example, an 18 page job will never print all 18 pages. It
may range from 15 5o 17 depending upon the amount of print data presently in the
printer network stack when linux aborts the connection. This is seem with
Postscript printers made by Sharp and HP.
Expected Results: All 18 pages should have printed with a network closure after
all of the print data was sent.
This is fixed in the current beta. I expect we'll do a bug-fix advisory in due
