Research direction

The issue names no source files or tests; start by reproducing the size(2,2) cases with an Epson TM-U220 on Ubuntu 20.04 and trace the printer size handling from the public printer API. Done means the reported size settings produce the intended enlarged output rather than normal-size text, with the behavior verified against the listed cases.
