You are right. Now that I'm thinking about it, it is probably not 
Printer.Resolution but the way the other functions are calculating their 
positions such as MoveTo, LineTo etc.

For the calculation of mm to printing pixels I use a function based on 
Printer.Resolution.

When I use gb.gui, line drawing etc. goes completely wrong. I had to 
fake a resolution of "60" to get proper positions here.

When I use gb.qt4, all positions are drawn correctly.

So yes, it is NOT Printer.Resolution, but the drawing functions.
