Solid ink printers are most commonly used as color office printers, and are excellent at printing on transparencies and other non-porous media. The letter form strikes a ribbon of ink, depositing the ink on a rotating, oil coated drum. Daisy-wheel printers operate in much the same fashion as a typewriter. Most teleprinters operated at ten characters per second although a few achieved 15 CPS. In either case, the letter form then struck a ribbon to print the letterform. Another aspect of printer technology that is often forgotten is resistance to alteration: liquid ink such as from an inkjet head or fabric ribbon becomes absorbed by the paper fibers, so documents printed with a conventional typebar mechanism while the Selectric used IBM's well-known "golf ball" printing mechanism. The choice of print engine has a substantial effect on what jobs a printer is suitable for, as different technologies are capable of different levels of image/text quality, print speed, low cost, noise; in addition, some technologies are inappropriate for certain types of physical media. Printers are routinely classified by the underlying print technology they employ; numerous such technologies have been developed over the years. Print from a variety of sources with connectivity options like built-in wireless networking and Bluetoothup to legal size. For professional-quality color and text documents, and lab-quality photos on the go rely on HP. With a variety of automatic editing features, output sizes and direct photo printing options, plus long-lasting HP Vivera Inks, HP products make it simple.
