I further tracked it down to see why the system which has the problem differs from the behaviour of a fresh install.
And I found the difference: I had a third party LO extension installed: LibreOffice E-Porto 1.0.3 from https://www.deutschepost.de/de/i /internetmarke-porto-drucken/e-porto-add-in.html#downloads . After disabling the extension in LO, this issue was fixed: Now I can print testcase.ods even when testcase.odt is already open. I assume the bug is in the E-Porto plugin, at least this should be very likely. So there is no bug in LO or in ubuntu packages, the bug seems to be in the extension. Issue can be closed then. ** Changed in: libreoffice (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1534927 Title: Calc wants to print wrong document and exits with unsaved changes to the document Status in LibreOffice: New Status in libreoffice package in Ubuntu: Invalid Bug description: How to reproduce: - open testcase.odt writer document - open testcase.odt calc document - Press STRG+P in calc => Result: Writer document is shown in printing preview - Press OK => Result: ===> Using 1:5.0.3~rc2-0ubuntu1~trusty2 from ppa, the writer document is printed ===> Using 1:4.2.8-0ubuntu3 from trusty-updates, there comes an error box with no text.
