As to the error codes...

 Code:
If DelPrinterConnection ("\\domain.net\IBBP5002-A4-4auf1") = 0
? "KONICA bizhub 250 für A4-Doppelnutzen-Duplex gelöscht !"
If @ERROR <> 0
		Color r+/w+
   		? @ERROR + " / " @SERROR
	EndIf
EndIf

Should be more like this....

 Code:
If DelPrinterConnection ("\\domain.net\IBBP5002-A4-4auf1") = 0
  ? "KONICA bizhub 250 für A4-Doppelnutzen-Duplex gelöscht !"
Else
  ? @ERROR + " / " @SERROR
EndIf


You have to write the @Error immediatly after whatever execution created the error, otherwise you are getting the result of output to the screen.

I would start by redoing your error traps and see what you are getting back.

Another thing to think about would be to see if a printer is already installed and if it is then skip that printer and move on to the next one/task.
