We can confirm this issue and also that the workaround with a higher timeout
value for CUPS works.
Our details:
Ubuntu 12.04 64 Bit
3.2.0-33-generic #52-Ubuntu SMP
Libre Office 3.6.0~rc4-0ubuntu3~ppa1~precise1
We performed a debugging session yesterday and observed that Libre
Office looses the connection to the CUPS server within 5 minutes:
- tshark on the CUPS server, observing the connection close:
353.291104 192.168.1.1 -> 192.168.1.115 IPP 245 IPP response
353.291352 192.168.1.115 -> 192.168.1.1 TCP 66 52363 > 631 [ACK] Seq=7064

[no further packages]

Ack=45385 Win=42272 Len=0 TSval=8400747 TSecr=8571337
- Other actions of Libre Office will be answered with a connection reset:
406.177739 192.168.1.115 -> 192.168.1.1 TCP 221 [TCP segment of a reassembled
PDU]
406.177767 192.168.1.1 -> 192.168.1.115 TCP 54 631 > 52363 [RST] Seq=45385
Win=0 Len=0
406.177840 192.168.1.115 -> 192.168.1.1 IPP 341 IPP request
406.177851 192.168.1.1 -> 192.168.1.115 TCP 54 631 > 52363 [RST] Seq=45385
Win=0 Len=0
- From this point of time on, Libre Office "knows" that there is no
connection with the CUPS server and doesn't open a new one.
- stracing shows the second printing attempt:

Title:
after certain time printing to cups stops working
Status in LibreOffice Productivity Suite:
Confirmed
Status in “libreoffice” package in Ubuntu:
Confirmed
Bug description:
in our institution we are running only printers through a cups server.
while freshly opened document prints well, after some time (few
minutes) clicking "print file directly" and menu item "print" do not
work any more. after close and open again, thing prints correctly. i
have checked what exactly is going on in such cases and logs on the
cups server don't show any submissions and/or errors so that the thing
is obviously stopped at the level of libreoffice.
