Printers
Four classifications of printers: p448
inkjet (bubble-jet)
laser
thermal
Use some from of impact and an inked ribbon to make an imprint on the paper. p 448
Impact Printers
Impact printers also use a paper feed mechanism called _______that requires special paper. p448
Tractor Feed
Is one of the oldest printing technologies in use. p448
Daisy- wheel printer
When the printer needs to print a character it sends a signal to the mechanism that contains the wheel. This mechanism is called the what? p448
print head
An electromechanical hammer called a _________ then strikes the back of the petal containing the character. p448
Solenoid
Their speed is rated by the number of ________ they can print. p449
(CPS) Character per second
This typewriter level of quality was given a name: p449
(LQ) Letter Quality
These printers work in a manner similar to daisy-wheel printers but instead of a spinning character-imprinted wheel the print head contains a row of pins (short, sturdy stalks of hard wire. p449
Dot-Matrix Printer
The main disadvantage of dot- matrix printers is their _______ which can be quite poor compared to the quality produced with a daisy wheel. p 450
Image quality
The output quality of such printers is referred to as _________ good mainly for providing your initial text to a correspondent or reviser. p450
Draft quality
(NLQ) stands for what? p450
Near letter quality
what does finishers do? p493
It does this by folding stapling hole punching sorting or collating the sets of documents being printed into their final form.
Typically attaches to the front of a laser printer and feeds in envelopes one at a time. p492
