Cannot get the datalogic qs6000 to scan 39 or 128 barcode

Sounds like you need an updated driver for your POS scanner.

Other than that, try checking the scanners setting your software and make sure it is set for 39 and 128 bar codes. There is usually a setting that will specify what codes the scanner is going to read.

You can always shoot an email over to the datalogic guys and see if they have any more input on the situation.
