An old daisy wheel printer would be a good example. In order of preference, we'd rank printers suitable to a law office with dot matrix being the lowest. The pros to dot matrix printers are that they can print carbon copies, drafts or second copies, and labels either better or less expensively than the other types of printers. They are also usually cheaper than lasers and print in color. The drawbacks are that the printouts sometimes smudge if they're not left to dry sufficiently.
Printing suffers grievously when in contact with moisture.
Assuming your office has no need for a color printer, that leaves laser printers as our choice for law offices. No matter what, there's plenty you can do to assist any sheet fed printer. Make the paper path as straight as possible. In our case this means using the flip-tray feeder on the front of our HP 6P and opening the back so that sheets are expelled at the back without being flipped. Regardless, the number is more significant than we knew.
