We have a situation that we have a library of 1000+ labels on a PC that we print on demand to a Xante through a batch file generated by our IBM iSeries. We would like to merge in a single line of data which would be a lot number/date code. The average label job is usually 1-2 sheets of 2-8 up labels and we run about 100-150 jobs per day. Is there a software package that handle the merge automatically without having to convert our PDF's our spending huge money on new software or hardware?
