Print form prints a solid black box!!!

[nick447923]

I am using a very simple print form procedure that I found on the internet. In one project it prints the form flawlessly. In another project it prints a solid black box!!! I'm not sure what is going on. Any assistance would be greatly appreciated.

GetFormImage()
pd.Print()

Me.Close()
End Sub

g.ReleaseHdc(dc1)
mg.ReleaseHdc(dc2)
End Sub
