Your print manager probably thinks there are keep out margins on your printer.
Typically, if you print to exact scales, you should get what you want.
I am assuming here that the drawing border goes right up to the edge of the paper size(?)
I do not use the print mamager and print to PDF using the Save-As Export functionality.
There are no scale options using this method. I can let the windows manager deal with Adobe instead.
one question that could be posed, however; does a scaled print through the print manager also scale the line weights?
