Ignore Data

The Ignore Data command causes the printer to ignore all data (except for the command to turn Ignore Data OFF). This allows comments or other that is not to be printed to be inserted into the document for information purposes.

Format:	^X<data>^A
^X	Ignore Data On Command. The printer will ignore all data after
	this command except for the Ignore Data Off Comand, ^A.
<data>	Data that the printer will ignore.
^A	Ignore Data Off Command. The printer will not accept all
	subsequent data received from the host.

Graphics Pass

A Graphics Pass begins with a Pass Start (^M, ^U, ^V, or ^E) and ends with a Graphics Pass Terminator (Pass Start, CR, LF, FF, ^-, or ^,). Any characters placed between the Pass Start and Pass Terminator will print as block characters. Also, all GPL Graphics Image commands, such as the Bar Code and Line Drawing commands must be sent within a Graphics Pass. Each Graphics Pass is treated by the printer as a set of data and instructions to be processed and printed, starting at the current paper position, before accepting any further data from the host.

Each pass begins at the current vertical paper postion and the left margin. From this point, the printer prints to the right and down the page.

NOTE: It is not possible to print above the starting point of a Graphics Pass. It is possible, however, to issue positioning commands within the pass which position the paper at any point below the start of the pass.

NOTE: When (LF, FF, ^*, ^,) are used to terminate a Graphics Pass, they lose their normal meanings, and become Pass Terminators such as ^-. When used outside the Graphics Pass they take on their normal meaning.
