Portable printer, I think that you can throw (gently) in a travel bag and take with you. Not going all the features of a "big" Printer necessarily, but better deliver high quality documents and photos. A portable printer is not necessary to be a workaholic - do not expect to print 500 pages of this at once, as is sometimes done in the office.
Most of these printers also have (optional) batteries. The list below all do. Honestly, if an interesting feature, how often you print in your car, airplane, or beach? For most people the answer is "never." You can save money by not buying these batteries use special and expensive.
We shared with Canon portable printers "Photo Printer" Only a class, and the "Full Featured printer can also print your full size.
Here is our first choice in each category.
For the photo printer category only, it is hard to beat the Canon SELPHY ES30. In fact, all models are small and portable Sephy, especially the "ES" series that I recommend. They are even built into the handle for true portability! The ES30 works with most memory cards (20 types) and features a 3.0 "LCD. Containing ink cartridges and paper will not miss a bit of ink or paper, and that aid in portability. It sells for $ 190, but Amazon often has rebates.
Canon iP100 Mobile Photo Printer is my choice of a "full-featured model. Yes, he calls" photo printer and print photos beautiful, but also does a great job of printing almost everything - here's the list: size Credit Card (2.13 "x 3.39") 4 "x 6" 4 "x 8", 5 "x 7", 8 "x 10", Letter, Legal, USA # 10 envelopes and photo stickers.
He also weight only 4.4 kg and operates from almost any voltage, making it ideal for international travelers. He obviously has all the connectivity options and should include IrDA, USB, direct connection to cameras and Bluetooth (optional).
No longer subject to hotel's Business Center, which always seem to join when you need it. This large print makes you a mobile office. About $ 300, although it is often good at Amazon.
There you have it, Canon laptop, my first two choices.
