Dot-matrix printers have no hardware page-rotation, so when PRINTER_A4
is enabled in the new printer.conf, txt2printr.sh rotates the ascii art
90 degrees in software before sending it, and photobooth.py caps its
live-preview viewfinder to an A4-landscape character grid (sized from
configurable PRINTER_CPI/PRINTER_LPI) instead of just filling the
terminal, so the preview matches what actually gets printed.
