	  Description: {HP DeskJet 550C/560C/6xxC series}
	  About: { \
		     This driver supports the HP inkjet printers which have \
		     color capability using both black and color cartridges \
		     simultaneously. Known to work with the 682C and the 694C. \
		     Other 600 and 800 series printers may work \
		     if they have this feature. \
		     If your printer seems to be saturating the paper with ink, \
		     try added an extra GS option of '-dDepletion=2'. \
		     Ghostscript supports several optional parameters for \
		     this driver: see the document 'devices.doc' \
		     in the ghostscript directory under /usr/doc. \
		   }
	  Resolution: {300} {300} {}
	  BitsPerPixel:  {3} {Normal color printing with color cartridge}
	  BitsPerPixel:  {8} {Floyd-Steinberg B & W printing for better greys}
	  BitsPerPixel: {24} {Floyd-Steinberg Color printing (best, but slow)}
	  BitsPerPixel: {32} {Sometimes provides better output than 24}
