The HP Photosmart 8250 is basically an replacement of the HP Photosmart 8450 (yes the model numbers seem wrong, but they are right). They both have a 4800x1200 dpi resolution, the Vivera inks which are very long lasting, and is still very fast at printing due to a new print engine. HP no longer uses the old tricolor (red, green, blue) print cartridges, but now six individual ink tanks that are bought individually or in a complete set. This allows you to only replace colors that are truly out and not just replacing the whole thing just because the blue is out. This new system means that 4 x 6 inch prints cost about 24 cents each. The 8250 is very fast when printing text documents(even with the optional two-sided duplexing attachment; sold separately), but it's also very quick at printing color pictures as well.
