maxine,
Without doing some Manual review, I don't remember any direct way to disable a printer port from the Panelview screen. However there probably is a way to do that using specific software packages. The first question is: what computer software program are you using the Panelview with? Now, does that program manual, in the chapter dealing with "Printers", "Printer Set-Up", or "Communications Port Settings", show any method that the printer port can be disabled using a programming line of code? If so, then you can set up a button on your Panelview screen to do the job. Otherwise, probably not.
