I have a Scanjet 5550c which came with the HP Director software.
My problem is that if I use ANY other software to scan, I dont have a way to turn OFF the preview. The twain driver comes up and automatically preview whatever is on the scanner. The main problem is that it previews with Millions of colors which takes a long time.
I have a software for document filling that will use the scanner, and it has no options for the scanning. All the options must be chosen on the twain driver.
If I use the HP Director software, I do have the option to turn off the preview and set the default setting to Gray Scale.
I already downloaded the alternate driver that HP offers, but that one has a different problem. This alternate driver automatically scans the document but in LINE ART which does not have shades of gray, resulting in a very bad picture.
As a solution I need to either change the alternate driver to scan in Gray scale or use the default twain driver with the auto preview off.
I searched on the registry but I could not find anything that suggested the settings for the twain driver.
I really appreciate any help, otherwise I will have to return this scanner and try a different brand.
