Crystal Reports printing from VB

Hi -
Does anyone know how to have VB code continue on after a Crystal Report was printed using the CrystalReport.1 Action = 1 ? Seems my program will wait for the printer to go thru it's communications and when I print 5 or 6 reports in a row, this makes the user wait until the VB program can continue. THanks in advanced.
Also, is there a way to close up "White space" in a crystal report if certain strings, are empty?
Ex- I have to print the contents of certain chemical blends and have Contents1, Contents2, ...(as database fields)If the latter ones are empty, I would like to close up that space. Is this possible? ALSO THanks for suggestions
