Add ReducedResolution mode (-R) for HP LaserJet P1005-1009

Unlike other XQX-based models, HP LaserJet P1005-1009 can't print
in real 600x600 DPI mode, requiring special 600x400 mode, in which
the rendering is performed in 1200x600 resolution, but the
XQX_START_PAGE header tells the printer to use 600x400 printing
resolution.
