I am running Libre Office 18.104.22.168 on Win 8.1, recent Thinkpad, with a Samsung ML-2850 series printer connected via USB. Whereas printing from WordPad, Firefox, ... works nicely, I cannot print from Libre Office (very simple text-only documents tested from Writer, Impress, ...)
-> printer signals an error (on this model this is only a red lamp, no further information), and it simply does nothing anymore (does not even documents from other applications that had been working before) unless I pull the power line. No error message on computer, no document in print queue.
I tried updating the driver, no change. Searching, I found suggestions for Linux which I could not translate to Win-Libre Office (changing printer language PDF/postscript, the described menues simply did not exist). I tried to set paper size to the (actually loaded) A4 instead the default letter in multiple submenues in Win and Libre, no change.
