HP DeskJet 890C. Some1 gave it to me, in excellent condition! This is a $400 printer!!
Owner had it for 3 years, I've had it for 1. This things is almost a rocket for an inkjet, and photos look beautiful.
HP DeskJet 672C. For my little brother, since I now have the 890C. Still going strong. 3 or 4 years old.
My next printer? If I can convince my girl to let me have it, probalby the Photosmart 1215 so I can use the IR to print from my Palm and the CompactFlash slot for my digital camera....though I usually have to touch up the photos anyway, and I don't print that much from my Palm........on second thought HP 952C!!
BTW the double sided printing is an option on all the 900 series.
Also BTW, this is something else I thought was neat and I'm actually considering: HPs
PSC 750. It's a scanner and a printer taken from the 952C. Comes in handy for *cough* copying homework *cough*
It can't use the double-sided printing module though, which I'd probably never use but it's neat to watch...
