There shouldn't be any need to print via bitmap export.
To set up a drawing, it is not necessary but helpful to first draw a rectangle as a frame in the size of the papersize, you may start it at the origin, coordinates 0,0, the red cross. Set that papersize also in 'Options' - 'Current Drawing Preferences'. Use and set your units, metric or imperial, inches, mm, m or whatever. It's easiest if drawing units and papersize units are identical, for instance mm and A4 ( 297x210 mm). If you intend a scale other than 1:1, for instance 1:100, in that case the drawn frame has to be 100 times larger.
Now set the line width in the pen options tab (at the top of the screen) to 0.25 mm (standard pen for thin lines) or maybe 0.5 mm and draw a simple line with the mouse somewhere within that papersize frame.
Go to print preview, set the scale (1:1 or maybe 1:100), click 'center to page' and click 'print'. Be sure you have in the following OS related setup the proper papersize set also.
If you don't succeed I can make you a template if you tell me your specifications.
