If you are working on a Dentrix system (Tested on G5) , and the user cannot do batch processor printing and are getting a “sch-3” error message along with nothing printing, this is the fix from Henry Schein:
1: start > run > services.msc go to print spooler, stop service and start service
2: hit control alt delete, and kill dxprint.exe.
3: Delete all sch-3 print jobs from within dentrix batch processor.
4: Reboot computer
5: test and should be working
