Mobile direct-thermal label printer

The Seiko Instruments DPU-S445 SERIAL is a hand-held thermal printer built for workers who need to produce labels and receipts on the move. It prints at 90 mm per second with an 8 dots/mm resolution and supports barcode symbologies including CODE128, PDF417, QR Code and Data Matrix. The unit weighs 1.08 lbs and measures 2.28" x 5.70" x 5.31", fitting easily into a belt pouch or tool bag.

Sustained mobile operation

The low-voltage thermal mechanism maintains consistent output during long shifts without ink or toner replacement. Internal memory of 4 KB buffers print jobs while the serial link and IrDA port keep the printer connected to Windows XP, Vista, CE 5.0 or Mobile 5.0/6.0 devices. The supplied battery pack and power supply allow continuous use across field sales, inspection, medical monitoring and warehousing tasks.

Serial interface requirement

This model communicates exclusively through an RS232 serial connection and IrDA; it does not offer USB, Bluetooth or Ethernet ports. Buyers whose host equipment lacks a serial port or IrDA capability will need a different printer. The package includes the DPU-S445 printer, battery pack, RS232 cable, power supply, power cable and utility software.

Questions about this item

How hot or loud does the DPU-S445 get during continuous all-day printing?

The low-voltage thermal mechanism runs cool and quiet with no fan, so extended use in mobile or desk settings produces minimal heat and near-silent operation.

What cable and power items must I already have to operate the DPU-S445 serial model?

The box includes an RS-232 cable, power supply and power cable, so no extra cables are required for a standard serial connection.

Will the DPU-S445 work with my older Windows XP or CE 5.0 handheld devices?

Yes, the supplied utility software provides drivers for Windows XP, Vista, Windows CE 5.0 and Windows Mobile 5.0/6.0, covering legacy field terminals.
