Options

AParallel
BFireWire 400
CUSB 2.0

Explanation

USB 2.0 provides the fastest speed among the listed options with a maximum throughput of 480 Mbps (Hi-Speed). FireWire 400 (IEEE 1394a) transfers at 400 Mbps, making it slightly slower than USB 2.0. Parallel ports (IEEE 1284) max out at roughly 1–8 Mbps depending on mode (ECP/EPP). DB-9 is a serial RS-232 connector typically running at 115 Kbps or less, making it the slowest option. For a SOHO printer, USB 2.0 is both the fastest available option listed and the most common modern interface.
