Series printers of the 7 pin dot matrix were the slowest. They were the console printers attached to the console, to print in the OS commands. I have seen Centronics, RS 232 c ports, which were faster and this particular DMP on the HCL's 8C-(R) consoles were the slowest. I do not know more. My experience limits upto this (1981) Note: Back in the 80s hobby computers (like Sinclair and Commodore) used their own printers and interfaces, and they were pretty slow.

The RS 232 interface is one of the standards used in serial communications. It uses serial signals (as opposed to parallel) to connect computers to devices like printers and modems.
An output interface is a device that show information or data from a computer. Some examples of output devices are printers and monitors.
Small Computer System Interface (SCSI) cables are used to connect computers to certain devices such as hard drives, tape drives, printers, CD drives, and scanners.
Serial printers are connected via the serial (COM) port of the computer. "Non-serial" printers are connected through another interface, such as the parallel port, USB, ADB. FireWire, etc...
RFID printers are used to print documents consisting of black and white ink. These printers are not common in households but can be used if one wants to.
Laser printers are the best option for at home use on the market today. Not only are they the fastest and have the highest quality, but they come in a variety of prices.
IEEE 1284 is the only answer but there is a catch: It can be used to connect to other devices as well but is mostly used to connect printers.
The old laser printers used He-Ne laser , and the modern laser printers use infrared laser .
