This section of the forum will certainly develop into the ever lasting struggle between Canon-, HP- and Epson-fanbois.
So I put my cards here on the table confessing that I'm currently using two Canon printers:
1. Pixma MP780, a all-in-one Din-A4 combination of scanner, Printer and fax-machine with 5 different colors (C, M, Y, Black and photo-black)
2. Pixma Pro 9000, a Din-A3+ pure photo-printer with 8 colors (C, M, Y, photo-C, photo-M, red, green, photo-black)
What I like: both are fast, price of canon ink is affordable, picture-quality seems very good to my eye, print-head doen's seem to clobber up. With the MP780:it has a DIN-A4 tray under the printer that can be filled from the front, which is very convenient.
What I don't like: the Pro 9000 uses the new inks with LED and a chip, they are not compatible to the ink in the MP780, although the cartridge seems to be the same. They charge 1 Euro more per cartridge and I have to keep two stacks of refill cartridges
Hint to Fans of other printer manufacturers: please start your own thread in this section, because I'm sure, that other companies also have nice printers
