According to the query application, we know that in the process of using the printer, the printer will leave some records, including printing time, file name, printer name and so on. This record is called "print record", which can record the information of all the files you print. The computer can view the print records of the printer, but only if the printer supports this function. For some newer printers, this function is usually built-in, while for some older printers, it can be realized by installing some software. So the computer has recorded it after printing it out.
