I use Desktop Editors on several machines (Linux Debian, Linux LMDE, Manjaro, Windows 10) alongside LibreOffice. Basically I like it very much. But now I had to print out a spreadsheet in DIN A3 format. I wasable to set it in the print settings, but my printer, an Epson Expression Photo XP 960, only printed in DIN A4. Is this a known bug or a limitation in the free Desktop Editors? Thank you for your information.

Hello @fgwalt

Please specify the version of Desktop Editors that you are using.
Also, have you tried setting the Size in Layout tab to A3 before printing?
