The computer printing technology that is used today is a far cry from that which was first used at the dawn of the computer age. Many of the older technologies are now obsolete, although they were at one time in widespread use. Other newer print technologies have replaced them and the way forward is forever changing as new computer print technologies come to the fore.
Obsolete Printing Technology
As time has passed and the computing powers of modern day PC’s have changed there has been a huge advances in the fundamental printing systems used by computers. The print technologies listed below are now obsolete, but did at one time play a large part in the computer printing industry.
In the early part of the evolution of computer printing there were a number of computer printers that were simply computer-controllable versions of current electric typewriter technology. These computer printers coul “type” faster than humans at averaged a speed of 15 characters per second.
One of the most popular computer printers of its time, this type of printer could be easily interfaced to all non IBM computers. Teleprinters were a little slower than typewriter printers and averaged about ten characters per second.
The original dot-matrix printers were extremely popular computer printers during the 1980’s. They were able to produce not just characters, but also images although be it of a lower quality. There were two types of dot-matrix computers available at this time, namely:
– Ballistic wire printers
– Stored energy printers
Did you know? Some dot matrix printers could be upgraded to print in colour. This made them extremely popular for both home and office use during the 80’s.
