We, wife & I use all the features of the 3330, the sheet feeder for scanning copying is great. We've run maybe 5 reams of paper through it, printing, scanning, faxing, copying. My biggest complaint is that it's huge, but we haven't had a minute's problem with it. While it's bigger than I like, it's footprint is considerably smaller than what the seperate components would be.
I unwittingly pricematched Staples for this printer against a 3300 @ Outpost, & got it for ~$400, honestly didn't realize it till I got home & looked more closely.
I dislike most of the consumer fax machines, especially the ones that use a film/ink system, they're a PITA to reload & expensive.
HP has software & firmware updates listed on their site for the 3300 series, looked up Carbonyl's printer & sure enough, they don't have the drivers listed for his printer...
