Total types of data that can be read by document reader are

Document readers are devices or software programs that can analyze and interpret written or printed text on a document. These devices can read different types of data from documents such as marks, handwritten and printed characters, and printed lines. Marks can include things like checkmarks or ticks that people might use to indicate a selection on a form or questionnaire. Handwritten characters are any letters, numbers or symbols that are written by hand, whereas printed characters are those that are produced by a printer. Printed lines refer to the lines of text that are printed on a page. Therefore, the correct answer is "all of the above" as document readers can read all of these types of data from documents.
