Printing Technology
The ZQ220 printer uses the Direct Thermal method to print
human-readable text, graphics, and barcodes. It incorporates a
sophisticated print engine for optimal printing under all operational
conditions. Direct thermal printing uses heat to cause a chemical
reaction on specially treated media. This reaction creates a
dark mark wherever a heated element on the printhead comes
in contact with the media. Because the printing elements are
arranged very densely at 203 dpi (dots per inch) horizontal and
200 dpi vertical, highly legible characters and graphic elements
may be created a row at a time as the media is advanced past the
printhead. This technology has the advantage of simplicity, as there
is no requirement for consumable supplies such as ink or toner.
However, because the media is sensitive to heat, it will gradually
lose legibility over long periods of time, especially if exposed to
environments with relatively high temperatures or in direct sunlight.
QR Code
The QR barcode includes human readable text URL, for example
www.zebra.com/zq220-info, which links the user to printer
information and short videos on topics such as buying supplies,
features overview, loading media, printing a conguration report,
cleaning instructions, and accessory information.
