Brother's HL-1250 tops the crowd with a maximum output of 12ppm. The 4MB memory is upgradeable to 36MB. Parallel and USB ports make it compatible with PCs and Macs. Like the Okipage 10ex, the Brother has a handy, large-capacity 250-sheet input cassette. If that's not enough for you, a second 250-sheet cassette can be added as an option. While its standard resolution is the usual 600 x 600 dpi, it boasts a true 1,200 x 600 dpi graphics resolution.
