For an HP Laserjet 2200D you're supposed to be able to set the density, but I find no HP configuration utility to do so. Just update driver, PCL 6, also downloaded driver for PCL 5E. Neither came with that small utility which, allegedly, has a slider to allow you to adjust the density of the printing. Only settings software allows are 600 DPI and ProRes 1200 (180 lpi). No sign of a configuration utility on Hp Website and good luck gettting to their tech support. Checked the CD that came with the printer; found no such utility on that either. I just want to make the print a little darker. Looks the same under 600 DPI and 180 lpi, still too light.
