Job Costing Print Event - Close Print Window

[leomylonas]

Hey Mike,
I'm looking for a way to close (or prevent from showing) the print window on the Print event of Job Costing.
I can set rtnAllowPrint to false, however, the print window still comes up (just blank)
How can I either close it or prevent it from showing all together? (This is a small portion of a much larger breakout script)
All the best.
