The usual solution would be to export your finished image in JPG or PNG
format, depending on the required resolution:  JPG makes much smaller
files but introduces some noise; PNG makes larger files with no added
noise or loss of fine detail.

Then, import your finished image into a desktop publishing application
like Scribus (Free Software), set the page size and image dimensions
there, and export as PDF for printing.

This procedure should give very accurate results, although I would
suggest carefully measuring a test printout to assure that the printer
itself is not introducing any errors in scale or placement that would
require adjustment to compensate.
