The toner is transferred to the paper and fixed by a heating process. Laser printers deliver crisp black and white and brilliant color prints.
While ink is standard in most conventional inkjet home printers, laser printers depend on toner and lasers for their output.
The laser printer was the first to be invented and was done so in 1969 by Gary Starkweather while working in the Xerox product development team. His idea was to use lasers to imprint an image onto a copier drum which would then be transferred onto paper. Hence, the name `Laser printer`.
Specifically, Gary Starkweather invented the laser printer in 1969 at the Xerox research lab in Webster, New York. Soon after, he transferred to Xerox Palo Alto Research Center (PARC) and developed a prototype for the Xerox 9700: our company`s first laser printer, which came to market in 1978.

Canon BJC-70 error message F 12
ANSWER : I am having the same problem, not only with my BJC-70, but also the equivalent problem with my BJC-80. Typically I am working at my computer, and the printer is powered up, but idle. All of a sudden for no apparent reason, it emits a series of beeps and returns the print head to the central position. The BJC-70 display Error F12. With the BJC80 you have to count the beeps. The problem seems to be caused by some sort of premature failure of the print head, due to an electronic fault. Sometimes, if the printer is powered down for a few minutes or longer, it will work normally for a short time after power is re-applied, but typically the problem recurs within 30 minutes, and this period of trouble free operation gradually reduces, until the print head will not work at all. The only solution is to replace the offending print head. You should, however, retain the failed head, in order to salvage any un-used ink remaining in the tanks. The new print head comes with full ink tanks. As soon as one of these fails, I replace it with an ink tank retrieved from the failed head. I don’t discard the failed head until both ink tanks have been retrieved.
