Ok, well I used to use the Dell all in one desktop.... I have a all in one Canon printer and when I would edit photos on the dell and print them, both matched..... I then upgraded on got an HP laptop... I also now have a canon pro9000 Mark II printer.... once I got this laptop, prints don't match what I see on the laptop on either printer.... Oh and always use and had used picasa.... hadn't given too much though until (I am learning photoshop) I edited a a photo and made the sky blue (my original was gray) and then printed, the print copy came out with a purple sky.... I had also emailed the pic to my mom and uploaded to facebook. My mom said the sky was lavender.... my husband now has my old dell and when he goes to fb and looks at the pic it displays same as my print..... when I go to fb on my phone and look at the pic, it's the same as print. Even minor edits in picasa made huge differences in contrast from what is displayed on my monitor vs prints or even slideshow on TV.
Previous to this I had tried printing on both computers and using different software.... prints were always the same, but different then my display on laptop. The pro9000 has calibration setting which I did... but no change to print.
I figured hooking up my son's monitor would make this issue simple by just purchasing an external monitor. However, since my son's displayed similar to my laptop, I'm disappointed and frustrated.
My laptop only allows me to adjust brightness and my red, green and blue colors... however, adjusting those colors has not yielded the results.. My laptop from what I can find doesn't have a contrast setting.
