Applications

The HP ThinkJet was introduced in 1984 and was one of the first commercially successful thermal inkjet printers. The 2225P was a serial/parallel-interface desktop model aimed at business computing environments of the mid-1980s, commonly paired with HP computers, minicomputers, and terminals of that era. ThinkJet printers were notable for their quiet operation compared to dot-matrix printers, which dominated the office at the time. Today, units like this are sought after by vintage computing enthusiasts, collectors restoring period-correct HP workstation setups, and technicians needing parts to service other ThinkJet machines. The parallel and serial interface options made the 2225P broadly compatible with a range of host systems of its era.
