Separate from printer.conf.epsondfx5kp.bak's fanfold arrangement: this
install runs the DFX-5000+ on cut A4 sheets (measured 70 lines x 80
columns) rather than wide continuous fanfold, and A4 mode is now known
to work and use the sheet fully, so PRINTER_A4=true here instead of
wasting paper in portrait. Also notes that the fanfold config's
11-inch DIP page-length setting doesn't match true A4 sheet length and
was causing a repeatable skip - the datasheet's 70-line/6lpi option is
the fix for this arrangement.
