int	$size	Size modifier for the image. Must be either `Printer::IMG_DEFAULT` (default), or any combination of the `Printer::IMG_DOUBLE_HEIGHT` and `Printer::IMG_DOUBLE_WIDTH` flags.

Mike42\Escpos\Printer::bitImageColumnFormat	(	EscposImage	$img,
			$size = `Printer::IMG_DEFAULT`
	)

Print an image, using the older "bit image" command in column format.

Should only be used if your printer does not support the graphics() or bitImage() commands.

Parameters

EscposImage	$img	The image to print
int	$size	Size modifier for the image. Must be either `Printer::IMG_DEFAULT` (default), or any combination of the `Printer::IMG_DOUBLE_HEIGHT` and `Printer::IMG_DOUBLE_WIDTH` flags.

Mike42\Escpos\Printer::close ( )

	)

Cut the paper.

Parameters

int	$mode	Cut mode, either Printer::CUT_FULL or Printer::CUT_PARTIAL. If not specified, `Printer::CUT_FULL` will be used.

Print and reverse feed n lines.

Parameters

int $lines number of lines to feed. If not specified, 1 line will be fed.

	)

Print an image to the printer.

Size modifiers are:

Printer::IMG_DEFAULT (leave image at original size)
Printer::IMG_DOUBLE_WIDTH
Printer::IMG_DOUBLE_HEIGHT

The functions bitImage() and bitImageColumnFormat() take the same parameters, and can be used if your printer doesn't support the newer graphics commands.

Parameters

EscposImage	$img	The image to print.
int	$size	Size modifier for the image. Must be either `Printer::IMG_DEFAULT` (default), or any combination of the `Printer::IMG_DOUBLE_HEIGHT` and `Printer::IMG_DOUBLE_WIDTH` flags.

float	$ec	Error correction ratio, from 0.01 to 4.00. Default is 0.10 (10%).
int	$options	Standard code Printer::PDF417_STANDARD with start/end bars, or truncated code Printer::PDF417_TRUNCATED with start bars only.

Exceptions
