Zebra printing in web dynpro/Adobe

Hello,

We have zebra label print designs in place (we dont want to design using adobe designer). Now we would like to enable subcontractors to print them online using web dynpro/Portal.

1. one way I identified is send the zebra spool as a file and save it in the local disks and print it using zebra printer.

Whats the better and efficient way to approach? How everybody is doing this?. Doesnt SAP have any solutions?.

Thanks ,

Raj.
