Printer prints labels, but print quality is poor.
23. Cause: Possible hardware problem.
Cure: Refer to the printer User’s Guide.
24. Cause:
Incorrect print media, for example, using direct thermal
paper while printing in thermal transfer mode.
Cure:
Load the correct print media for your printer and application.
Confirm that the software is setting the printer for the correct print
method.
25. Cause: Using Value Grade media in a printer set up for standard
media.
Cure: Either switch to standard media, or set the printer up for
Value Grade media.
26. Cause: Incorrect parameter in a VARIABLE DARKNESS
command. This can happen when using a different printer than
the one for which the format was originally written. Some older
printers use a different value range for VARIABLE DARKNESS
than currently-manufactured printers.
Cure: Experiment with the VARIABLE DARKNESS command to find
the best setting for your printer and print media.
27. Cause: Printer speed setting is too high. Some print media do not
print well at high speed.
Cure: Use the appropriate VARIABLE command to reduce printer
speed, or try different media.
Print is stretched or shrunk vertically.
28. Cause: Dot time in header line is incorrect.
29. Cause: Label format was written for a different (typically, an
earlier or later model) printer.
Cure: Try another value for dot time. If designing a turnkey software
package, provide for user adjustment of dot time. Allow for printer
limitations in this regard. For example, Barcode Blaster LS and
Blaster Advantage printers only support dot time 100.
