The only main features on the back are the power plug and the removable metal casing where upgraded memory can be installed. This case is held on with two small philips-head screws because it is not something you will remove often (or ever in most cases).

On top of the printer, most notably, is the large output paper tray. This tray has a capacity of 250 sheets of regular weight paper. The rest of the top of the 770ND, less the area for the control panel, is a large door that opens up to reveal the fuser unit. In front, the slightly angled control panel has a very comfortable 4-line LCD display with two function keys beside it. Left to that is the circular navigation/selection pad and lastly a cancel button and power button. The circular navigation pad has a blue illuminated ring around it which will cycle to show printer activity. When in standby mode, the screen will show the toner level for each of the four cartridges as well as a quick legend for what the basic buttons do.

When the front is opened, you'll see the rather large home for all four of the toner cartridges that the 770ND uses. Each of these cartridges has the drum built-in and a standard length cartridge will run you about 7000 pages. However, in typical fashion of buying a new printer, the included cartridges are rated at half that. The main transfer belt on the inside of the door is rated at 50000 prints before it needs replacing. The printer itself has an overall monthly duty cycle of 120000 pages.

If you need more paper choice, or simply more paper capacity, the included 500 sheet paper cassette can have two additional 500 sheet cassettes added below it. The printer driver will allow you to choose which cassette you are pulling paper from for your current job.

Printing from a network, where the printer has jobs thrown at it constantly, requires a printer with lots of RAM to keep up. When a job is sent to the printer, it is stored in RAM until it's turn to be printed. This keeps the load off the host computers and reduces network congestion of computers continually trying to restart print jobs until the printer frees up. The 770ND has 256mb of RAM out of the box, but can be expanded to 512mb if required. With the option for an 80gb hard drive, the printer can not only handle larger jobs, but can also store jobs as well.

Samsung advertises this printer at 32ppm speeds for both mono and colour prints. Duplex printing is also a feature supported right out of the box on this model.
