I downloaded an excel sheet from the web and exported it to Libre Calc and altered column widths a bit and then went to print.
It stubbornly seems to insist on printing in portrait.
Am I doing something wrong? I just select the whole area and then go print selection define and that’s it.
It’s only a small sheet. I could upload it that facility is available.
You can set/adjust the page orientation for the printing in the Page Style applied to the actual Sheet.
