The HL-5150D produces crisp text and graphics at up to a fast 21ppm. You do not have to sacrifice quality, either. Resolutions reach 2400 x 600 dpi, thanks to Brothers HQ1200 technology. The HL-5150D automatically switches between PCL6, BR-Script 3, Epson FX and IBM Proprinter emulations. Connectivity is equally as flexible, with automatic switching between Parallel and USB 2.0 interfaces.
