In respect to this, do copiers store information?
Copiers scan your documents to create replicas and then they store that information on an internal hard drive. Estimates say that multi-function copiers (which pretty much means all the copiers you'll be using) can hold as many as 25,000 documents.
Similarly, do inkjet printers have tracking dots? Monochrome laser, LED and inkjet printers lack the yellow toner necessary to print the dots, and therefore do not produce these markings. Experts have identified yellow dot marks on documents from many printer makes, including Xerox, Hewlett-Packard, Toshiba and Canon.
Beside this, can a printed document be traced?
All organisations can track timecode for printer requests, to see who is sending a document to be printed when. The printed yellow dots could be a hedge against counterfeiting - if the purported date of the document does not match up to the data confirmed by the dots, then you know it's a fake.
Can you photocopy onto card?
For times when plain paper copies simply aren't durable enough, copying your image directly onto card stock may be the best solution. With basic knowledge of your specific photocopier, you can easily copy an image from plain paper to card stock.
