Tried using my mum's Kodak Photodock to print some photo's, thus avoiding the hassle of ordering prints online: if I only want one picture I don't have to pay £1.50 postage. Tried changing the ink cartridge and the printer refused to release it. Tried unscrewing and fiddling but it still wouldn't come out. Went online and kodak's troubleshooting faq said that with these symptoms it should be sent back to Kodak for repair.
So I bought a Canon CP510, a basic 6x4 inch photo printer in Jessops. The reviews I had read told me that the print quality was very good and apparently the prints will last for 100 years. I hate inkjet printers, cheap and nasty things and the ink cartridges always need replacing and cheap clone cartridges always have at least one blocked jet. Yuk. Hence this 'dye sublimation' thing. I also like Canon, my canon scanner and laser printer have served me well.
The CP510 is a basic model, it doesn't have an LCD display or memory card slots, it is designed to print either from a pc or directly from a camera (it has a retractable usb cable). The more expensive models have more features for printing without a pc but I am unlikely to use these.
When I got it out the box I was perturbed to see that it was obviously the same technology and mechanism as the kodak. Looking through the troubleshooting faq it didn't mention the problem I had with the kodak so hopefully they have fixed it.
I printed some photo's out and was disappointed with the results. The resolution was fine but the pictures were muddy, the colours dull. I fiddled with the settings a bit, increasing brightness, contrast and saturation but I didn't get results that were anywhere near as good as prints I get from photobox. The paper has two tear-off stubs at either end and when you hold the finished print you can feel the perforations and it is irrationally annoying.
On the whole I must say I am disappointed with it. It is ok for knocking out quick prints but for populating photo albums I would prefer to use photobox.
