Takes a licking and keeps on working
This has been an incredible workhorse for us. In addition we own a HP Lasarjet III which is also still in service - but has had occasional service to maintain it. While we are thinking of upgrading the Lasarjet, we are going to keep the Okidata 321.
Our office has used this printer for over 10 years in moderate volume per month. We've never had to have it serviced and had very little problem with paper feeds
