That is called Laserjet Printer We back at 2003 , this is my first time to know about printers ,computers and anything around inside the company offices.Of course i know already about computers at that time. but there is one device or a machine thats call out my attention. A medium size square type like box besides the desktop pc. At that time i was with my Supervisor and ask him about that device .And he answered me that it is a printer. An HP printer (i am not a brand endorser 😁)And thats all answer my curiosity on how the documents are printed.
