If you like some movement, best would be to display an animated gif file in an image control, here you find some gif files of printer, copy or fax machines:

Just drop an image control on the form, set the picture property to the gif file image source and make the image Visible = .F. at first.
When starting the "copy" method, run code like this:

THISFORM.imgCopyanimation.Visible = .T.
THISFORM.Draw()
*-- Here run the code that does the copying or whatever.
THISFORM.imgCopyanimation.Visible = .F.
