Summary: this printer is OK, as long as you don't try to use all of its functions. It does not work with Ubuntu, it holds temporary changes, like using the manual feed permanently...needs all defaults restored after printing an envelope...as a scanner, the settings are counter-intuitive making duplex almost impossible, don't buy this printer new, I'll sell you mine cheap and it's barely used.
Summary: I will come back and write a longer review. Over the 2 years that I have owned this, i have come to regret this purchase over and over. Need to re install drivers every once in a while. Scan to PC feature does not work well. You have to initiate the scan from the pc. Cannot initiate scan from machine. Even better. If the toner is low, it gives errors when you are trying to just scan and save as pdf. Pro. Wifi connectivity is a big big plus.
Summary: I bought this printer and at the beginning I was happy with it. Wireless, printing and scanning worked fine. Then it quickly ran of of toner. So, I bought a new Samsung toner from Staples. When I replaced it, the printer was always giving the status "Replace Toner" and it did not print anymore. There were no way to delete the status message ! (even with the brand new toner) I think this is a design flaw.
Summary: Wireless function does not work properly. Very cumbersome installation process. Once installed it works fine. Then the printer falls asleep - by design, according to tech support. Does not wake up on print job being sent to it via wi-fi, you need to actually walk up to it to wake it up by pushing power button. Even that does not work consistently, because the printer forgets its own assigned IP. I fought with it for two weeks. Gave up and returned to the store.
Summary: I tried to set up the wireless connection from the printer to the router, but no luck. I've called the tech support four times. Every one basically let me do the same exercise. After the first time called, the rep told me he would escalate the case and have their next level support team call me in 2-3 business days. 8 days passed, but no one ever called me. I checked back and the case was still sitting there. This is how Samsung handle the support case! Unbelievable!!!
Summary: The printer is yet to be used because it is 110v and it was purchased to be used in Africa with 240v. Most printers these days come with 110-240v power rating to be used all over the world (at least HP printers are) so when purchasing the printer, it was just assumed to be 110-240v because the voltage rating wasn't written on the printer details on Amazon or Samsung's websites.
Summary: Don't buy this if you are on 10.6.5. I have had it less than 2 months and upgraded to 10.6.5 and it broke ALL the software with this. Their horrible tech support refused to even escalate me to Tier 2 or offer to contact me when drivers were available even though I'm a registered "Owner" on their site.
