  • Hi, I'm looking at the black toner cartridge MLT-D203E which your site says is for a Samsung SL M4020ND printer. My machine is a Samsung ProXpress M4020ND. Could you confirm that the MLT-D203E cartridge is the correct one please? Many thanks, Shirley.

Samsung SL-M4020ND Printer Review

Expert review of the Samsung SL-M4020ND printer

Our Verdict:

The Samsung SL-M4020ND printer from the ProXpress series is a simple and straightforward entry-level laser printer that can help minimise operating costs without compromising quality and speed. Designed for increasing productivity, the Samsung SL-M4020ND mono laser printer can handle a wider range of professional documents, but it can only print in monochrome and lacks expandability options that could make it even more efficient.


The Samsung ProXpress M4020ND features an industrial frame that measures 366mm wide, 262.5mm tall, and 365.6mm deep. It’s heavy, weighing 10.18Kg and is powered by a 600MHz processor running on 256MB of memory. The control panel is small and minimal, with a numeric keyboard and a two-line display. The interfaces are high-speed USB 2.0 and Ethernet. Paper is handled mainly by a 250-sheet cassette and a 50-sheet multi-purpose tray. The output bin on the SL-M4020ND monochrome printer can handle up to 150 sheets at a time.


The memory capacity of the Samsung SL-M4020ND laser printer is expandable to 512MB. Users can expect to accomplish more in a short space of time because of the high-speed printing technology, while quality is maintained because of ReCP technology, which improves readability through the enhancement and sharpening of thin lines and smaller details. The Samsung SL-M4020ND ProXpress monochrome printer has a multipurpose tray that supports more media types like cardstock, transparencies, cotton, envelopes, and archive sheets. Two-sided printing is a built-in feature to help save paper. Users can reduce their cost-per-page by installing an ultra high capacity Samsung SL-M4020ND black toner cartridge for maximum productivity gains.


The functions of the SL-M4020ND printer are limited to a single user or a small workgroup. Options for expansions are very limited. The display screen is too small, which can make on-board operation of the ProXpress M-4020ND more difficult. The IEEE 1284B parallel connector is only optional.
