Pros: Compact, light, easy to use, Battery pack w/ charger, Bluetooth, No Wires need here.
Cons: Battery Cradle not worth the extra money.

I bought this in August. I also purchased the battery pack, and now I am totally wireless. This unit also has blue tooth wireless. Cost extra, but worth the money.
I take it on the road when I fly or drive on a trip. I print my E-tickets, go to meetings and nobody has a printer, when you need one. I have replaced the black, but I have not run out of color yet. It is very compact to pack your printer & laptop in the same brief bag. Even with the battery pack.
Bring your cords just so you can recharge it. But the cord is very light and small, not bulky at all, like others
Just get the Canon Portable Kit LK-51B comes with charger. Battery goes into the charging unit, and then connects to the back of the printer with screws. The cradle just gets in the way. All the cradle does is charges the printer on it backside, but you CAN NOT print anything.
