Laser, ink-jet and thermal
Printers that form images without physically striking the paper are called non-impact printers. Examples: Inkjet printers – spray tiny droplets of ink onto paper. Laser printers – use a laser and toner to create images. Thermal printers – heat-sensitive paper changes color to form the image.
I don't understand the question. "With a speed"? Inkjet printers spray ink onto paper. If you mean "with high speed", inkjets are notoriously slow, perhaps you're think of the new memjet technology. Search youtube for "memjet" and prepare to be impressed!
The output devices used include computer displays, impact and nonimpact printers, and electronic communication devices for EDI and e-commerce.
Thermal Printer
-- inkjet -- laser
Yes, many do, especially networked printers.
An impact printer, is one that has a mechanism that makes the letters physically strike the paper. Two examples would be a daisy-wheel and a golf-ball printer. Non-impact printers use either jets to quirt microscopic dots of ink onto the paper, or tiny electrical impulses to 'burn' the characters onto the paper. Two examples would be an ink-jet printer and a thermal printer.
Dot-matrix printers and Line printers.
In a search for computer printers, the first two found in a search cost a combined total of $269.98. This is for two different brands of All-in-One printers.
Amazon and eBay are two of many stockists of Verifone printers. They also stock the till rolls used by the printers and it is wise to stock up on these.
No, thermal and line printers are two different things. "Line" printers are referring to a form of "Dot-Matrix" printers. "Thermal" printers burn a special paper to form characters and symbols.
Impact printers use a 'daisy wheel' or a 'golf ball' to physically press letters through an ink ribbon onto the paper - think along the lines of an old typewriter. Non-impact printers 'squirt' microscopic drops of liquid ink directly onto the paper.
