When can we start printing voucher more than 3 per page? Or is there any alternative way in doing that with use manager ver4.5?

Export the CSV and create your own template or print method...

I wrote mine in VB and print it to a "Star TSP600" recept printer...

I create barcodes, serial numbers Etc, for "inventory" and tracking...

You can even centraly admin the ticket creation..

IE use a prefix in the user ID. then based on that ID, pick a different printer to print the ticket..

A "help desk" cound handle any number of hotspot locations...
As long as the application can "see" the printer, you can service it..
