NOTE: The PRINT potentiometer adjustment will affect the darkness in all of the
command code speed ranges, i.e. if the PRINT potentiometer is adjusted for
lighter print, the darkness will be lighter in all speed ranges selected by the
command code.
PRINT SPEED
The other method of controlling print quality is by controlling the speed at which the label is
printed. This adjustment is made only on an individual label basis using the Print Speed
command code. For more details on this command, see the “e” and PRO 3Printer
Programming Reference. Changing the print speed allows the user to control the amount of
time allowed for print element cooling before the media is stepped to the next print position. It
is especially critical when printing “ladder” bar codes (bar codes printed with the bars parallel
to the print line). When printing a “ladder” bar code, it is important to allow the head to cool
sufficiently before stepping to the next position. If it does not have sufficient time to cool, the
bar will be “smeared” on the trailing edge.
The Print Speed can be set using the LCD panel or with the Print Speed software command.
The software command will override the any setting entered using the LCD panel.The other
method of controlling print quality is by controlling the speed at which the label is printed.
This adjustment is made only on an individual label basis using the Print Speed command
code. For more details on this command, see the “e” and PRO Printer Programming
Reference.
