LPRINT and LLIST now output to a printer device or file instead of the
screen. By default, output is appended to LPT1.TXT in the current
directory. Use --lpt to redirect to a real printer device (/dev/lp0,
LPT1 on FreeDOS) or a custom file path.
Includes full PRINT format support (semicolons, commas, TAB, SPC,
PRINT USING) and LLIST with line number range parsing.
