Ramon:

You can select a particular printer with the SelectPrinter Method:
The print setup dialog should come up with
loCRW = CREATEOBJECT("CrystalRuntime.Application")
loRpt = locrw.OpenReport("fully qualified path to your report.rpt")
loRpt.PrinterSetup(0) && 0 current window..

If you need to set to a default printer for a particular printer without user intervention:

oRPT.SelectPrinter(cDriver, cPrinter, cPort)

Hope this helps ---
