Printouts come out with wrong size, 94% while printing from CD 2020 for Mac!!!! Why?

I have used Corel Draw on Windows for many years (since version 3) and I never had an issue with the size of my printouts.
Now when I have installed CD2020 for Mac I did not bother to checkout this but when I measured the parts of a drawing for a scale model I realized that something were quirky, the size was not 100% it was just about 94%.

I tried the following for problem isolation.
Made a new simple drawing in version 15-format to make printable for both my windows and Mac version.
Just a simple square 100*100 mm
Printing on the same printer, a net connected Canon MG 7550

-Printed from Corel Draw X5 in windows - Comes out fine 100*100mm
-Printed from Corel Draw 2020 in Mac - Comes out wrong size 94*94 mm

Then exported the same file to PDF-format
- Printed from Adobe reader in Windows - Comes out 100*100
- Printed from Adober reader in Mac - Comes out 100*100

So from what I can see there is no problem with the drivers or settings for the printer in Mac environment
The problem seems to be in Corel Draw for Mac......

Are there any settings in Corel Draw that I need to adjust?
