When comparing handwriting from collected specimens, however, it is important to collect contemporaneous writing, or material that was written around the same time period as the document in question. Some fax machines also allow the user to reprogram certain formatting characteristics, which may make it more difficult to accurately discern the make and model of the source machine. Questioned Documents. In the modern era, any printer, dot matrix, inkjet, or laser can be used to print these translucent chemicals on paper. Transmitted faxes are often printed at a relatively low resolution, compared to documents that are printed or photocopied. Questioned documents may include markings from rubber stamps, embossed seals, watermarks, or other mechanically-printed marks.
