Twain or Wia

  namtas 14:57 27 Mar 2006

Anyone give me a quick answer on this.

Installing a Epson Scanner on a Windows XP system, and I have the choice of driver Twain or WIA, read up some stuff about merits of each but can not make my mind which is the best. Any offers.

I always install the twain driver,to be honest never had a choice of twain/wia but i suspect they both do the same thing.

From what I have read WIA (windows image acquisition) is for Windows ME, so I would go with TWAIN.

TWAIN definitely.

Now find that only WIA will work, I encountered the problem when trying to set up Omnipage 15, It finds and brings up three option Wia, Twain and (Twain + Wia, warns not to use this) but Twain gives an error report and a red cross. Only by selecting WIA will it run.

Is their any reset for this error could it be a remanent as I was yesterday trying to install a differnet scanner and failed with the Twain error and assumed that the drivers were not compatible as they were older. Now bought another and it is this installation that is the problem. I dont really want to a restore system as Omnipage is a bit longwinded to reinstall.

Any help on where to look to clear the driver would help.

Do you really need Omnipage? Omnipage is an OCR application. I have never used an OCR because it takes so long to train it and it is quicker (for me at least) to type it in.

Give us another clue? What is the Epson scanner you are trying to install?

Well ok but I am not a typist and I have a lot of documents to both copy and convert. I do not find that the new versions of OCR need to learn, It scans reproduces and converts text almost instantly.

It is scanning but now that I learn that Twain is better this being stuck with WIA is really bugging me.

I am using the Epson 3490 scanner on Windows XP
