  • invert: If non-nil, the output colors will be inverted
  • padding: Number of blanks cells to print around the QR code (default 2)

qrprinter.print_qr

qrprinter.print_qr( qr, [options] )

Print qr to stdout using ANSI escape sequences.
Alias of qrprinter.print_qr_ansi.

qrprinter.print_qr_ascii

qrprinter.print_qr_ascii( qr, [options] )

Print qr to stdout using ASCII characters.

qrprinter.print_qr_ansi

qrprinter.print_qr_ansi( qr, [options] )

Print qr to stdout using ANSI escape sequences.

qrprinter.print_qr_utf8

qrprinter.print_qr_utf8( qr, [options] )

Print qr to stdout using UTF8 block elements.
