Page Print Commands - Configuration
Datamax-O’Neil printers can operate in two separate modes: Line Print Mode and Page Print Mode.
On Power Up the printer defaults to Line Print Mode. In this mode, all data is printed from top to bottom as it is received. In Page
Print mode, the canvas is constructed in advance and the form is printed afterwards. This allows for positioning of text,
barcodes, lines and rectangles at specific X and Y coordinates and also at specific angles – 0, 90, 180 and 270 degrees. The
rendering process of the page is done in printer’s memory.
Page Print Mode can be used to design a certain template and replace only variable data during communication.
