Advantages and disadvantages of daisy wheel printers?

"Daisy wheel" printers were an early form of electronic typewriter. They were limited because the mechanism was noisy and not all that reliable, and that when the "daisy wheel" print head become broken, they were cumbersome and expensive to replace. If you wanted to change fonts, you had to change wheels. If a letter (on one of the petals of the daisy) become broken, it was not uncommon for the broken letter to be lodged deeper in the machine where it could cause more damage.

IBM's similar "type ball" technology was quieter and more reliable.
