Printer prints a random pattern instead of the expected
bitmap.
Cause: The printer is set for a different pitch or width than the
graphics file was designed for.
• Cure: Before sending graphics to the printer, send a dummy
label format consisting of a
header line
,
WIDTH
command,
PITCH
command, and
END
statement. This assures that the printer is set
properly before sending the graphics data.
Cause: The graphics file is too large for the available memory
space.
• Cure: Calculate available printer memory and confirm that
your graphics file will fit. Remember that the available memory is
cut in half when using background graphics mode. If you are near
the memory limits, you may have to rewrite the graphics file.
Random dots or lines appear on the finished label.
Cause: The host system is appending unwanted end-of-line
terminators to the graphics data.
• Cure: Print your graphics format to a file and then upload the
file to the printer instead of sending the data directly to the printer.
• Cure: Check your development platform’s documentation to see
how you can control end-of-line termination.
Cause: The graphics file is too large for the available memory
space.
• Cure: Rewrite the file as required.
Part of the graphics image is garbled or blank.
Cause: The graphics file is too large for the available memory space.
• Cure: Rewrite the file as required.
