⚖️ Expert Verdict

Two legends of the 9-pin world. The OKI 3320 is built with a level of industrial grit that's hard to beat—it's the absolute unit for longevity. The Epson LX-350 is a more compact, modern, and energy-efficient equivalent. While the OKI is a proper tank, the Epson wins for being easier to manage, cheaper to buy, and much more compact for small desks. For most modern businesses, the Epson LX-350 is the winner for its better balance of price, size, and reliable 9-pin performance.

What Owners Are Saying?

OKI Microline 3320

OldSchool_Len
"Absolute unit of a warehouse printer. We've had one running for a decade and it’s still going. A bit of a faff to set up on a modern PC, but for continuous forms, it’s a legend."

Epson LX-350

Milly
"Most frugal way to print receipts and delivery notes. The ribbon lasts for millions of characters. A bit basic, but it’s a reliable bit of kit that won't let you down."
