It supports Adobe PostScript Level 2 programming functions and produces printed pages at a rate of up to 12 letter-size pages per minute. The LaserWriter 12/640 PS printer supports 600 dpi resolution. FinePrint can be selected to smooth text and line art. FinePrint technology gives the printer the ability to print dots of different widths, producing crisper text and graphics. The printer also supports PhotoGrade printing. This is a technology that enables the LaserWriter 12/640 PS printer to print photographs with as many as 97 shades of gray. PhotoGrade can designate more than one level of gray for each pixel by controlling the size of the dots. Photographs printed using PhotoGrade technology retain a higher level of detail than that achieved by other 600-dpi laser printers. The imaging system runs two Page Description Language (PDL) interpreters: Adobe PostScript and Hewlett Packard's Page Control Language (PCL). An intelligent PDL sensing algorithm can switch between PDLs while the LaserWriter 12/640 PS is printing. The LaserWriter 12/640 PS printer works with several network interfaces simultaneously by means of its three I/O ports: the Ethernet port, the LocalTalk port, and the parallel port. The I/O processor supports active port switching among the three ports.
