Select a Print Mode
Use a print mode that matches the media being used and the printer options available. The media path is
the same for roll and fanfold media.
To set the printer to use an available print mode:
•See PRINT MODE.
• See the ZPL Programmer’s manual,
^MM command. See About section for information and support
links for your specific printer model.
Print Modes
• TEAR OFF -— This mode (default) can be used with any printer options and most media types. The
printer prints label formats as it receives them. The printer operator can tear off the printed labels
any time after they print.
• PEEL — Label Dispenser Option only. The printer peels the label from the liner during printing and
then pauses until the label is removed.
• CUTTER — Cutter Option only. The printer cuts between labels after each one is printed.
Adjusting the Print Quality
Print quality is affected by the heat (density) setting of the printhead, the print speed, and the media in use.
Experiment with these settings to find the optimal mix for your application. Print quality can be configured
with the Zebra Setup Utility’s ‘Configure Print Quality’ routine.
Note • Media manufacturers may have specific recommendations for speed settings for your printer and
the media. The recommended speed may be lower than your printer’s maximum speed setting!
The darkness (or density) setting can be controlled by:
• The Set Darkness (
~SD) ZPL command (consult your ZPL Programming Guide).
•See the Manual Print Darkness Adjustment.
•See the Darkness Control.
If you find that the print speed needs to be adjusted, use:
• The Windows printer driver or application software such as ZebraDesigner ™ .
• The Print Rate (
^PR) command (consult your ZPL Programming Guide).
Use the printer’s ‘Print Quality Report’ (also known as the FEED Self Test) to print a range of labels that
help you identify print DARKNESS and SPEED settings for optimizing general print and barcode quality.
See the Print Quality Report (FEED self test) for details.
The printer’s media settings can be verified by printing a Printer Configuration label. See the Test Printing
with the Configuration Report for more details.
The maximum distance the automatic media type detection and sensing checks can be reduced using the
ZPL Maximum Label Length command (
^ML). The minimum distance should be no less than two times the
longest label being printed. If the largest label being printed was a 2 by 6 inch label, then the maximum
label (media) length detection distance can be reduced from the default distance of 39 inches down to 12
inches.
Note • See About section for information and support links for your specific printer model.
