Is it possible to print out my entire board to scale over multiple pages? My board layout is 500mm long and I need to print it out on standard A4 printer paper. Obviously this won’t fit but I can’t seem to make KiCad split it into 2 pages that I can stitch together. It seems to be unable to print more than one page at all, as far as I can tell.
I believe you are correct - KiCAD’s “Print” feature can not extend an output across multiple pages.
I would try using the “Plot” feature to convert the board image to a *.PDF file. Then I could use the “Poster” and/or “Scale” features in Adobe Reader’s “Print” dialog to split the image across multiple pages.
