Digital BW, The Print

Perhaps someone can help me with this.  I have a Minolta DiMage 7, when I
take a photo it looks good on the camera display and in Photoshop.  However
after I save it and attempt to print it, the photo is pixilated.  I can
think of 3 reasons for this

1.  Adobe is messing the image up when it saves

2.  Windows print wizard is messing things up

3.  My HP DeskJet 648c (even with Kodak Glossy Photo paper and a photo ink
cartridge can not do the job).

I really think item 3 is the problem, and am thinking of getting a Canon
I905 printer.  Does anyone have any experience with these and can let me
know how photo like the images printed really are? Thanks.
