The HP Officejet 100 Mobile Printer is a colour inkjet printer specifically designed to be a portable model for mobile users such as estate agents and insurance agents. It delivers, but for a high initial price, as well as high ongoing ink costs.
Offering features that are tuned for simplicity and portability, the HP Officejet 100 Mobile Printer is small and solidly constructed. It weighs 2.5kg, including the battery, so carrying it is about the same as toting around an all-purpose laptop. If you know that you'll always have AC power available, you can shed about 180g by leaving the battery behind. USB and Bluetooth connectivity are standard. The top cover folds back to create a 50-sheet rear vertical feed, but the printer has no output tray. Controls are minimal, limited to power, cancel, Bluetooth on/off, and paper feed.
Speed is not the HP Officejet 100 Mobile Printer's forte. Printing black text and simple monochrome graphics at default settings, the unit averaged a lacklustre 3.7ppm on a Windows PC and 3.6 pages per minute (ppm) on a Mac. Printing small colour photos on plain paper, the HP managed a competent rate of 2.7ppm, but moving to nicer settings on photo paper slowed it considerably to 0.5ppm. Our full-page photo printed on the Mac clearly pushed the OfficeJet 100 past its comfort zone, as it took a tortoiselike 5.5 minutes. A switch to draft mode sped things up considerably: text pages flew out the front.
The HP Officejet 100 Mobile Printer's impressive print quality makes up for the wait. Text was nearly laser-like in its precision, and monochrome graphics looked smooth. Colour graphics printed on plain paper appeared slightly washed out and had a distinct bent toward pink and orange, most noticeable in flesh tones. Moving to HP's own photo paper resolved most of those issues.
Ink costs are higher than average, although not the worst we've encountered.
