Can’t seem to print on a 4 x 6 index card with my HP OfficeJet 6700 printer. I don’t see anywhere in LibreOffice where I can tell the printer I’m using a 4 x 6 card. I can tell LibreOffice that the page size is 4 x 6 but it doesn’t flow through to the printer. I get an error that says something like " paper size does not equal the size that the printer senses"
You have to set the 4x6 card format in the printer properties. Goto Menue:File->Print. The first tab shows all your installed printers, select the one to use and then click on Properties-button and in the menues there setup your format.
DO NOT use the Print icon this sends it directly to the printer!
