officejet 4500 g510n, wireless, windows 8, readiris pro 14.
ocr scanning works fine using the ocr software supplied with the printers cd.
readiris has no particular Twain for the 4500 but has "hp twain others"
i have uninstalled and reinstalled BOTH printer software and the readiris program
Readiris refuses to recognise my printer "Cannot open Twain default source" and "The scanner does not respond"
readiris support has not responded to my query sent 5 days ago - makes me wonder if their software is the same as their 'support' - pretty useless!
any suggestions please

The way I understand it, readiris only works on HP scanners or All-in-One printers do not offer OCR software. It adds that functionality to scanners and printers that do not already have it. Since the 4500 already has OCR software built in, the readiris software will not work. I am not 100% certain about this, as I have only dealt with the HP OCR software, but from what I have read, that is my understanding.
