portable printer

I have / had an HP portable printer .
This year I left it in Mexico at my house .I left the printer , an extra ink cartage , paper , my tripod and a few other items I take every year .
The Airlines dropped the weight from 76 to 50 lbs and started charging for a 2nd bag .
Anyway , I want a new portable printer .
Anybody own a good one you would suggest to friends ?

Do you need to have a 81/2 x 11 paper size or 4x6?

I am looking for a 4X6 or a 5X7 [they are / were hard to find and paper was even harder .] The one I had , I had to cut down 8 1/2 X11 and then trim again . It gave a tab to hold pictures by while drying - it committed suicide - I didn't cut paper right , it got stuck and when I pulled , the printer jumped to floor .
I got the HP because it took the same ink cartage as my HP 7350 .
I was looking for one before I went to Mexico - no one carried batteries for the ones they had .
Plenty of time now , so I'll get other opinions [I hope .] I did check at Mac show last Jan . HP , Epson and Canon - no one sold a portable and desktop that took same ink cartage.
No package deals that came with both printers and battery .
They don't have camera shows here for some reason , southern Calif but not northern Calif for some reason .
