Aaaah yes - that was it:

Private myPrinter As Printer


in a SUB somewhat later:

myPrinter = New Printer As "_myPrinter"

myPrinter.Print()


BUT!

Public Sub _myPrinter_Begin()

This way it works here, but the SUBs are still visible when the 
completion list pops up in another module... Is that correct?
