Zebra Technologies R402 manual Operation & Options, Thermal Printing

Operation & Options

This section helps you get the most from your printer.

You must use programming to control many of the printer’s functions. A few examples:

■The ~JL command controls label length.

■The ^XA^MTD^XZ command changes the printing mode to direct thermal; the ^XA^MTT^XZ command changes the printing mode to thermal transfer.

■The ^XA^JUS^XZ command saves the new settings to flash memory.

For detailed information about creating labels using ZPL II, refer to the ZPL II Programming Guide or visit our web site at www.zebra.com.

To improve print quality, changing both print speed and density may be required to achieve the desired results. Your application’s printer driver provides control of the speed and heat (density).

Thermal Printing

The print head becomes hot while printing. To protect from damaging the print head and risk of personal injury, avoid touching the print head. Use only the cleaning pen to perform maintenance.

The discharge of electrostatic energy that accumulates on the surface of the human body or other surfaces can damage or destroy the print head or electronic components used in this device. You must observe static-safe procedures when working with the print head or the electronic components under the top cover.

You must use the correct media for the type of printing you require. When printing without a ribbon, you must use direct thermal media. When using ribbon, you must use thermal transfer media. The printer’s ribbon sensor detects motion of the supply spindle.
