The Epson WorkForce WF-100W is a portable A4 inkjet printer designed for those who need to produce professional documents while on the move. It utilizes an Epson Micro Piezo print head and pigment inks across all colors, allowing you to achieve a high resolution of 5760 x 1440 dpi. When connected to power, it prints monochrome pages at 7 pages per minute and color pages at 4 pages per minute, though these speeds adjust to 4 and 2 pages per minute respectively when running on its integrated battery. Measuring 309 x 154 x 61 mm and weighing 1.6 kg, this compact device fits easily into a bag. It features a small 3.7 cm color LCD for easy navigation and supports a wide range of paper formats from standard A4 and Letter to envelopes and photo paper up to 300g/m². You can connect via USB 2.0 or wirelessly using Wi-Fi Direct and Epson Connect, which includes support for Apple AirPrint and Google Cloud Print for printing directly from your mobile devices. The built-in rechargeable battery can be powered up in 3 hours via USB or an AC adapter, providing enough energy to print approximately 100 monochrome or 50 color pages. This makes it a practical tool for business travelers or field workers who need to print contracts or reports in a client's office without relying on external hardware.
