During the years, this has become obsolete, although computer equipment with these ports still exist, mainly for compatibility, as these printers still exist in some offices, however, there are also office automation programs designed to give instructions on these ports.
The way to identify these ports is simple, as they are quite large and are usually located above the video (VGA) port of older computers, it has a large number of pins, 25 in total, of which 8 as data transmission target, 4 for data output control and 5 for input, the others function as mass.
