Are you certain that it would be too slow in VEE? Do you have a
performance spec in mind? I am reminded of a quote once posted to

Yes we used the small Zebra Printer. It is controlled by an ASCII-File with
some control characters. Take care not to use a to printer object. Use a to

Has anyone used a barcode/label printer with HPVee?
If so how did you accomplish this?
