How Can I code in vb.net to change save path?

[yene]

this is my code:
printFile = "fileName"
printDoc.PrinterSettings.PrintToFile() = True
printDoc.PrinterSettings.PrinterName = "doPDFv7"
printDoc.DocumentName = printFile
printDoc.Print()

I have question, can it support to change the directory of savepath?

thanks!
