Review on JetDirect Print Server J7934A UUS by Broderick Shetler

I use an old HP 4300 printer and it works without any problems - ie it hasn't been noticed. The original part for the 4300 series of printers was the 615n. I replaced this part with another 615n about 7 years ago and the replacement recently came loose so following the advice in these reviews I decided to try the 620n and hope it lasts until I replace the printer . The essence of this review: 620n works in the 4300 line of printers and, judging by the reviews, is more reliable than the original 615n. Of course, I can't personally judge relative reliability without waiting at least seven years.
