Using Wasp Barcode Fontware & Crystal Reports 8.5 (with report distribution addon) we have been able to print barcode labels by entering a sales order number, line number and quantity.
CR uses an ODBC link to DBA database files
BKARINV (SO-A screen 1)
BKARINVL (SO-A screen 2)
BKICREF (IN-L-C)
to pull name, p.o. number, our p/n, their p/n, part description & rev. level. (we use the last field in IN-L-C for rev. level)
We also utilize the UPS printers for outer carton labels. We bought some Zebra printers for inner pkg.
Note: Report writing experience is VERY helpful.
