OKI ML380 24-pin dot matrix printer; fasted speed 240cps at 15cpi and 160cps at 10 cpi.
A letter-quality dot matrix printer with the low running costs associated with this design and a low purchase price. The 24 pin head gives reasonable graphics handling - although it certainly isn't fast.
There are a few points in favour of letter quality dot matrix printers:
They don't suffer from the inkjet tendency to clog when not used
- the printheads have practical lives measured in years whether they are used or not.
- the ribbons last a long time even when installed in the printer
Tractor feed paper is a bit more troublesome to load than cut sheet, but once in place it feeds very reliably.
Dot matrix (and other impact papers) can produce multi- part stationary, so it's easy to keep a copy of everything.
