My wife gave me a HP Deskjet 450CI for XMAS 2002 as I was travelling a lot and it seemed a decent solid printer that was compact if a little expensive. I was looking for a basic printer that could do most basic printing in a compact form. I was not looking for awesome performance in any aspect.
The good: Printer prints decently and quickly. Printer is pleasing in shape and compact.
The bad: Printer does not handle cardstock (fairly common deficiency here) or full size photo paper.
The ugly: Printer suffers NUMEROUS jams (to the point of being unuseable) - paper is pulled in approx an inch, jams, then software comms problems begin. I have seen the problem discussed in a number of online forums. This apparently is a design problem relating to the pinch plate which may have been corrected in printers made after July 2003. If you are in warranty, HP will fix the problem but if you are like me and the problem occurs after the warranty expires fixing this design defect is on you.
Bottom line: Before buying: 1. Make the seller take the printer out of the box so you can check the production date (only located on the serial tag on the bottom of the printer) (how many vendors will do this?). 2. Verify that "no kidding" this design defect has been corrected.
Postscript: I have been highly satisfied with every HP printer I have had until this one. This printer has not yet gone through a single complete ink cartridge and has never run card stock or photo paper. I do not want to deal with repairs so today I scavenged the ink from this one - threw away the 450CI - and installed the ink in my new HP PSC1350. The jury is out on the PSC1350 for now.
