I am looking for a simple character string I can use to pass to a printer. It does not have to be anything fancy, something as simple as" hello world" across the top of the page. I have looked through the HP references on the site and I am not able to put anything together. Nothing I have been passing has seemed to work, and I am hoping with a known good string I can get the printer to print something. I have a barcode scanner which will be connected serially and pass through a parallel converter before it gets to the printer. So I will need a raw serial string or text string which I can convert to PCL Language that the printer will understand.
