Laser, ink-jet and thermal
Yes, they are.
Laser/LED printer and Inkjet printers for a couple.
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!
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.
The output devices used include computer displays, impact and nonimpact printers, and electronic communication devices for EDI and e-commerce.
Dot-matrix printers and Line printers.
Thermal Printer
-- inkjet -- laser
Yes, many do, especially networked 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.
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.
Do you mean: "Do laser printers print in color?"?There are two types of laser printers:1. Black&White Laser Printers - they DON'Tprint in color.2. Color Laser Printers - they DO print in color.
