Problems between LO and CUPS

users
#1

LO connects to CUPS on start not when you want to print So if you have LO open for a while the connection to CUPS  will time out. You need to set your CUPS timeout short enough  so that it will time out eventually but long enough so that  CUPS doesn't drop the connection in normal use.

Hi Malcolm,

I haven't had the same issue as described in this thread, but it may be related. I'm running Ubuntu 13.10 and LibreOffice 4.1.5.3 presently. This situation has happened with all Ubuntu versions and LibreOffice versions in the last at least year and a half, as I update Ubuntu every 6 months, and update LibreOffice running the latest stable version from The Document Foundation as they come out. It has happened on at least 4 different printers. If I am printing multiple copies of a document in LibreOffice, lets say 10 copies, LibreOffice instead of sending 1 print job to the printer telling the printer to make 10 copies, it sends 10 different print jobs to the printer printing 1 copy of each. All other programs I run in Ubuntu send 1 print job for the multiple copies. I found this out by attempting to print 50 copies of a two page document about a year and a half ago, which overwhelmed the printer, and then Ubuntu. If I make a pdf of the document, and then through the document viewer print 50 copies of the same document, it sends one print job telling the printer to print it 50 times. So there is something with LibreOffice and printing in Ubuntu at least, which works differently than all other Linux programs I have used in Ubuntu.

Hi Don,

Looks like that's your report :slight_smile: So it's known and I think you're even a
commenter on it. It's been inherited from OOo it looks like.

Best,
Joel

This is bug fdo#56344 which appears to have been resolved in CUPS v1.7.0:

The problem as originally reported in this Users mailing list thread /may/
be related. If it is, then upgrading to a newer CUPS version will be
required as the problem was not with LO.

Best wishes, Owen.
