Be sure to check the print quality of bar codes with a bar code
verifier or scanner. If you do not have a verifier or scanner,
check the bar code visually. A bar code that is IN SPEC will
have complete bars and clear spaces. Small alphanumeric
characters will look complete. A bar code that is IN SPEC
may not look as good as one that is too dark, but it will have
the highest scan rate.
For highest scan rates, make sure there is
adequate white space before and after the
bar code. Also, a darker bar code does not
mean it will scan better.
Reducing Imaging Time
Imaging time is the time it takes the printer to image the data for
the first label after the printer receives the format and batch
packet. There are several ways to reduce the imaging time: send
formats and configurations once, use a batch quantity of zero, or
update batch fields.
◆
If the formats use the same check digit scheme, you only need
to send the check digit scheme once.
◆
Send formats once and use the batch update field to change
information on the label. Using a batch update field reduces
the imaging time, because only the fields that change are
imaged. All other fields remain the same as the last queued
batch.
