【Oki Electric Industry】 OP4w/ML4w

The OP4w and ML4w were ultra-compact printers for Windows that printed four pages per minute. Adopting a print process that enabled toner recycling, the printers used a compact photosensitive drum to fit into 191 x 310 millimeter (w x d) footprint that was smaller than an A4 sheet. They were also designed for comfortable desktop use.
