barcode printing problems

rbuser

Hello,
I have problem when I print more than 20 barcode the printer print few
white labels in random sequence (empty labels),
- why this happened and how to fix it ?

- I noticed that all the print job is sent to the printer is there a way
to send only part of the job and after it finish send another ?
for ex: printing 50 labels send them as 10s

Printer: Any Zebra model with 16 MB memory
RB version: 10
Delphi: 7
windows: xp pro

Thanks

Hi Isaac,

This is not a known issue with ReportBuilder. Be sure you are using the
latest printer driver for your specific printer. If these are separate
labels being printed, you could possibly add a search criteria that updates
for each 10 or so labels and creates a new print job for each report.
Another option would be to manually create a page list and send it to the
printer device for as many times as it takes to complete the report. Check
out demo 124 in the \RBuilder\Demos\1. Reports\... directory for an example
of that.

After a month and I still have this problem unsolved I try many other
zebra drivers and different pcs, zerbras and cables but the problem
remains now I have a problem with my boss the only thing I discovered
that after printing large amount of labels if I turn the zebra off and
on again the problem did not occur soon!! is it suppose to unload the
memory automatically ?

please advice
thanks

Hi Isaac,

ReportBuilder does not communicate with the printer directly. It makes
standard Windows API calls that in turn communicate with the printer driver
which controls the printer. It is the job of the driver to interprete these
API calls correctly. In other words, all code for printing reports to a
printer is the same regardless the printer type.

Check your printer driver software to be sure there is not a setting that
will clear out it's cache. Perhaps take a look at the manual or check
on-line for others that have had this problem.
