However, I always had 'fixed' checked, which causes that button to disappear.
Perhaps the more fundamental question is: what does the scale factor x:y really mean? I would assume it means something like the ratio of printer-units to drawing-units. Even so, it appears I need something between 1:100 and 1:120. However, none of those values seem to make sense. What am I missing here???
My goal is 1 inch on the printed page equals 10 feet in the drawing.
I'm clueless then.
You could export to pdf in Print Preview mode with the same settings. Some pdf viewers have a tool to measure distances in the pdf, as if on paper.
And you can also print out from the pdf, to see if a Print to fit appears in the windows printer settings, and if the printed size is right.
Scale 1:120 should be right. One inch fits 120 times into 10 feet.
The scale setting is a bit quirky and often doesn't want to stick to the value you have type in. I'm not sure about the proper procedure at the moment.
OK. I found an old version of my printer driver from 2014. I completely removed the latest version. I then installed the old version. Viola! Now 1:120 scale prints a 1" symbol correctly. Oy! Every since HP took over support for Samsung printers, their software has been crap.
