canon rebel camera..pro 9000 printer. Pictures printing darker than my monitor shows?

Im not sure if this is a quick fixer..But i just got a new canon pro 9000 printer..and after i take my files and use my photo shop program...when i print them..they look very much darker..than what my finished photo looks like on my dell monitor? It really sucks..cause after i take the files off the camera into the computer..I slightly fix the pictures i like. Then print them out...only to have them not as nice as when i fixed them on the computer. My old Hp printer didnt have this problem..is there something im missing?

Possible printer/paper profiles are still set for HP or not set correctly? Do you have a print preview and if so how did that look.

i removed all components of the hp.. I just set of the canon as to the factory default settings..and print..it looks good in the preview..its just after it prints..there is more detail on my screen and its brighter..

Did you turn off color management on the printer or Photoshop. When there is 2 color management running the resulting pics come out dark.

i have no clue what im doin..lol..but after wastin alot of canon pro paper and ink. I had a little success. I took a picture..no photo shoppin...went to print it..in the prefrences for the printer settings..i set the color correction to : none- came out with yellow tones. Set to matching driver , linear : better , lighter good tones. Set to matching driver, standard: it was vibrant colors..but a little to shaded. So i guess after i experiment for a few...it will get better...
I did these pics on letter size..as i didnt want to waste any 13x19 paper till i get better..any input will help..thanks!!
