Thank you for answering my questions. I really hope to hear that this works for others then. Could you imagine how much time you may have saved? And ultimately solving a lot of these destination scan errors...I can't thank you enough for your contribution.
How could you tell the difference from one printer's file to the next? I just checked my files and after finally finding the TWAIN_32 under the Windows folder of the C drive, my one little file was named the same as yours, so I am just being curious. Also, which HP printer was giving you the most trouble? I have to wonder if the files had a similar name as your printer and that's how you could tell the difference. I only have one HP printer on this computer.
