You need to run the OCR programme (omnipage or textbridge) or whichever one you have and then open the scanned document in it. You will probably find you will have to "teach" it before you get much sense out of it. Once that has been done you can save it as an editable document.
Some time ago I loaded "Form Pilot" from a magazine cover disc. I scan in the blank form then the program lets me enter details in the relevant positions on the form. Sorry I don't know how to set up a direct link but a Google search on - Form+Pilot - should give you more information. Norman
Scan the form as a graphic into your wordprocessor. Turn off text wrap, then set tabs and adjust line spacing to fill in the form. Unless the form has to be reused many times, don't mess about with OCR.
