I use VB6.0 and Crystal Report 4.6 with Access 2000. I upgraded drivers and create RPT file without problems. I set Crystl32.ocx parameters in VB app. and OpenReport. Then I get error 20520 - Print Job Already Started. You are trying to start a print job that has already been started. This can happen if the user starts a print job and then tries to start printing again before the previous printing has finished. I tried everything, doesn't work.
