HP 1200 HP PCL/PJL reference - PCL 5 Comparison Guide - Page 139

Additional features include: • Simplified Control Panel. The IEEE-P1284 ECP port described below allows front-panel simplification and the elimination of DIP switches. The DeskJet 1600C control panel is similar to that of the LaserJet 4L, with one button and four LED indicators. • IEEE-P1284. This bi-directional enhanced capability port (ECP) allows most printer features to be monitored and controlled through Microsoft Windows or a DOS remote control panel shipped with the product. In previous HP printers, PJL provided some job-level status and control, but PJL is embedded in the data stream, synchronous with the printer description data. With the implementation if MLC (Multiple Logical Channels) on the ECP and MIO 6.0, the printer can be controlled and monitored on a separate channel, asynchronous to the data stream. PJL still provides control that must be synchronous with the data stream. • ENERGY STAR. The printer lowers its power consumption if it has not been used for 15 minutes. • Out-of-Ink Sensing. An LED on the control panel lights when a pen runs out of ink. • MIO. Modular I/O interface with auto-sensing I/O configuration. • JetDirect. Optional network cards: Novell, TCP-IP, LocalTalk, EtherTalk, and third party. • PostScript. A SIMM upgrade is available. • Optional Media Source. An optional sheet feeder tray is available. • Media Detection. Automatic detection of media size and media type (transparency). ENWW Printer-Specific Differences 2-91
