Rhino8 printing to 1:1 scale not accurate

Good morning, we in the office many times need to physical print shapes 1:1 to check with the real object, we are using an HP DesignJet T520. After Rhino8 has been released it looks like there are several issue with the rhino printer not accurate dimensions, rhino PDF to 1:1 isn’t working at all, the documet size and the units are allway changing between mm and inch whenever I close and open againg the printer page.
Until you release an update that resolves those bugs we are obligated to move to Rhino7 every time we need to save PDF or print something.
Thank yuo for your attention, I hope soon to see an update.

Just to give you some informations more about print to PDF.

You can see ther’s no way to print a PDF with 1:1 scale, even choosing bigger document dimensions it never fits. The result stays the same.

It doesn’t work with a custom set window neither, how the scale can stay set to 1:1 if I random create the window area.
