Chapter 2 Half-Dot Mode (Double Density)
Half-Dot Mode (Double Density)
The Half-Dot Mode causes the printer to print at 120 DPI horizonta lly (the
standard print density is 60 DPI). Printing at 120 dpi results in dark er printing
and reduces the stairstep effect of diagonal lines. It is most often used to
improve barcode readability. The Half-Do Mode can be toggled ON and OFF
within a Graphics Pass using the command:
Command ^KF<data>^KF
