⚖️ Expert Verdict
The OKI 3320 is a durable 9-pin staple, but the Epson LQ-590II is a significantly more advanced 24-pin tool. The Epson is faster, quieter, and produces much higher resolution text that's actually legible for fine print on contracts. While the OKI is a reliable old tank, the Epson LQ-590II wins for its superior character quality and modern connectivity options. For a professional operation that cares about its output quality, the Epson is the clear winner for its refined impact technology.
