My gripe with Lexmark is that they charge you absurd amounts for relatively small ink tanks. Epsons I don't like b/c they're loud and need to "warm up" before they start printing. Also, with Epson, Lexmark and Canon, you have to use the expensive photo papers to get the highest quality prints. HP, while the best results are with the photo paper, the results using plain paper are fairly impressive.
So, that means I will once again stand by HP. Cheaper inks (large cartridges), no warm up time, very quiet, super reliable.
