2D printing to laser printer at 1:1 is not scaled properly in Rhino 8.26

I noticed that the print had the correct width across the page (x axis), but was short in the length (y axis). I used the print dialog box and set scaling at x=1.0 and y=1.01, which should have corrected the issue. I had to increase the y to 1.200, which should be way over the value required to compensate for the scaling issue.

I exported the drawing to Illustrator. Printing at 1:1 scale was accurate. The x and y values do not need to be adjusted for the image to be correct.

Has anyone else noticed this print scaling issue with Rhino 8.26.25349.19002?

Dunno, have you checked the laser printer driver’s settings?

I just printed out a 150mm square at 1:1 on my inkjet here in SR 8.26 as well as the 8.27.25357.11371 SRC and it measures exactly 150mm x 150mm. I’m on Windows though.
