The OKI B431dn is a professional A4 monochrome laser printer designed for business offices, workgroups and professional environments requiring fast and dependable black-and-white document printing. With print speeds of up to 34 pages per minute, it is well suited to everyday office printing as well as larger document workloads.
The printer delivers up to 1200 × 1200 DPI resolution, producing sharp and clear monochrome text and graphics. This makes it suitable for printing reports, invoices, letters, forms, business documents and other professional paperwork where clear output is important.
Automatic duplex printing is included as standard, allowing documents to be printed on both sides of the page without manually turning each sheet. This can help reduce paper consumption and is particularly useful when producing multi-page reports, presentations and longer office documents.
Connectivity includes Hi-Speed USB 2.0 and Ethernet 10/100 Base-T, providing both direct and network printing options. The Ethernet connection makes the printer suitable for shared office environments where multiple users need access to the same printer.
The OKI B431dn features a standard 250-sheet paper tray plus a 50-sheet multipurpose tray. This provides convenient paper handling for everyday printing while allowing different media or paper types to be loaded through the multipurpose tray.
With a monthly duty cycle of up to 60,000 pages, the B431dn is designed to handle regular business printing and demanding workgroup workloads. Its combination of fast print speeds, automatic duplexing and network connectivity makes it a practical office printing solution.
The printer is equipped with a 600 MHz processor and 64 MB memory, with the memory expandable for improved handling of larger or more complex print jobs. This helps provide reliable performance when processing multiple-page documents.
The combination of 34PPM printing, 1200 × 1200 DPI resolution, automatic duplex, USB and Ethernet connectivity makes the OKI B431dn a versatile choice for offices and professional workgroups requiring efficient monochrome laser printing.
