Woosim Porti W25, W40 & WC40 Mobile Printers

The ultra-slimline Porti W25 portable printer is only 30mm high making it ideal for carrying in the Executive's briefcase or Test Engineer's tool kit. The 832 dot/line resolution means it can be used as a portable printer for use with a laptop computer, or for graphical output from a piece of test equipment or monitor.

The internal rechargeable Li-ion batteries can be charged from a vehicle or AC adapter and a choice of RS-232C, TTL or Bluetooth interfaces make it compatible with most systems.

The W40 has a similar specification but is cheaper to run courtesy of a slightly taller profile to accommodate a longer, 40mm diameter roll and the use of the more popular 112mm wide paper. The WC40 model adds an integrated magnetic card reader.
