I have a HP Photosmart A310 and the camera reads ERROR when it’s connected to the printer, and I select the print option. I don’t know why!
Is there anyway to connect the camera printer to the computer if it won’t work with the camera?

I have an Hp Photosmart R725v model digital camera. I use it constantly and transfer pics from it to my computer constantly. Well just recently I plugged the usb camera cable into my computer and all of a sudden it is no longer recognizing the camera. It gives me the message “USB Device Not Recognized—One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.” It literally worked one day then the next day didn’t work anymore.
I need some ideas on what to try to get it to work again. I dont think there is anything wrong with my USB ports because I have an HP printer plugged into the same port that I was using to plug in my camera and it works fine with the printer. How common is it for USB Camera Cables to go bad? Should I buy a new one?

I have an HP Photosmart A430 Camera with the printer.
How do I charge it? Can I charge it with the printer?
I used to charge it with the printer but I don’t remember how I did it.

I have a Canon Ixus 80 camera and a computer running on Vista. I’ve lost the usb cable for my HP photosmart printer, and want to put pictures onto my camera’s memory card so I can print them.
Problem is, although these pictures were taken with a canon camera, when i go to copy them onto my camera, an error message pops up about how the file has one or more properties outside of device limits. When I tried before, i couldn’t see the picture on my camera and couldn’t print it off properly from my photo printer when i copied it onto my camera’s memory card. The error message says that I should use a program to change the file properties, but I don’t know what program to use and what properties to change. The files are all jpeg., just like those on my camera. Could the problem be to do with the size of the file? All advice is appreciated.
