poor print quality with airprint iPhone.

Hi I am having an iPhone 4 and I am also having an HP Photo smart e-AiO. I am able to get airprint working from my iPhone, though; the quality of the printout is dreadful. I have been trying to print photos taken from the iPhone 4. What I have been trying is that emailing the printer with the similar photo from my iPhone 4 and the quality is fair in that case. Has airprint been compressing the file and printing it in inferior quality as compared to the original one? Is it the problem associated with the glossy photos paper? Can anyone tell me what the actual problem is? Any help will be appreciated!

Can you tell me that Which Photosmart you are using? For pictures taken on your phone, the image that is original which I think should be directly sent to the Printer. Are you using the Photos app to print your picture? Any additional information you can provide would be beneficialI am looking to help You but I will need some of the information.

Also You will have to let us know that wht paper you are using?
