Hewlett-Packard OfficeJet G55 Scanner is designed with separate paper paths, which allow printing while you are scanning images; you can make copies while sending print jobs or scan while copying documents. The copier also works as a stand-alone device to produce fine quality monochrome or color copies in 600 x 600 dpi resolution at copy speeds of up to 12 ppm in black and 9 ppm in color. You can also select from 1 to 99 multiple copies. The reduction and enlargement options range from 25 to 400 percent. All the best qualities of the copier translate to the scanning and printing features as well. The flatbed scanner features resolution of 600 x 3,600 dpi (and up to 9,600 dpi enhanced) with 26-bit color and 8-bit gray scale (256 levels of gray for improved contrast). It includes optical character recognition (OCR) software for easy editing and revisions. The printer produces pages with 600 dpi resolution in black and 2,400 x 1,200 in color, with print speeds of up to 12 ppm in black and 10 ppm in color. The unit holds 150 sheets in the input tray, handling plain paper, ink-jet papers, labels, transparencies, glossy and matte photo paper, iron-on transfers, and more.
