Pros: Duplexing is a nice feature, works on my Mac as well. Decent workhorse printer.
Cons: It says it's out of ink after 2000 pages, regardless of how much ink is in each container, forcing you to upgrade all of your ink cartridges. This is unfair and unjust! Lots of people are having his problem, just seardch he internet for the stories.
Summary: I have multiple printers, I only use this one for color, I had the same problem with the waste toner tank, I have less than 1000 pages on this printer. Samsung said it is out of warranty. Bought a Samsung DVD Burner, everywhere specs says support Divx, did not work. Called Samsung, they said specs are wrong it does not support divx. Samsung is a low level brand. HP from now on. Avoid Samsung and the hipe.
Summary: I purchased this machine for a small office and was very satisfied initially. However, several problems starting to surface after about 1 year - all of which are typical after I researched for solutions. First, the sensor that monitors the level of the waste ink cartridge becomes very weak to the point that it will not shoot through the cartridge. My fix was to remove this portion of the cartridge and seal with tape.
Excerpt: "...had my CLP 510 from Samsung for just on 12 months so I feel I have gotten to know it quite well...in this time, I've only printed a total of 13,576 pages - thats the TOTAL from 12 months of use, NOT per month - this is very light use. I mainly use it for printing text with graphics included on the same page...not photos, just drawings etc. I'll start by saying that the prints per min quoted by samsung in a joke (most manufactures quoted specs ...
Summary: The CLP-550N was at such a competitive price I hunted for it with 3 of my suppliers - and 7 weeks later there were still no confirmed stock of the printer. I eventually opted for the CLP-510, but I imagine the 510, 510N, 550 and 550N are all the same printer but with NICs and more memory. Toms Hardware had this rated very well and I read some other reviews that gave this printer a good rating.
