In recent years, forensic document technology which primarily focuses on tracing a document's origin or identifying forgeries has advanced quickly. Commodity scanners and a computer are used in this technology to carry out the required evaluations. Printer, forgery, and scanner identification have been the main topics of recent document forensics research.The requirement for printer inspection in questioned document examination has arisen in the modern period as a result of the growing use of printers in document generation as opposed to handwritten documents and the counterfeiting of documents produced by different printers.Inkjet printers, laser printers, and photocopiers—three frequently used document creation devices were studied under a microscope to determine how they differ from one another. Based on characteristics seen in the characters in the papers, the suggested approach can distinguish between documents created by various sources. Thus, it can also be used to identify documents that have been altered and come from a combination of various sources.
