CAUTION Note EconoMode The EconoMode setting uses up to 50 percent less toner than standard mode printing by reducing the dot density. However, EconoMode does not extend toner cartridge component life. EconoMode, which can be thought of as "draft mode," can be selected from the control panel (print-quality menu) and through some software applications and printer drivers. The default setting is OFF. HP does not recommend full-time use of EconoMode. If EconoMode is used full-time, it is possible that the toner supply will outlast the mechanical parts in the toner cartridge. EconoMode does not affect print speed or memory usage, or extend the life of the toner cartridge. Input/output Parallel interface The formatter receives incoming data through its bidirectional interface (IEEE-1284). The I/O provides high speed and two way communication between the printer and the host, allowing the user to change printer settings and monitor printer status from the host computer. The user can configure the HIGH SPEED item in the control panel menu. The default setting, YES, allows the I/O to run at the higher speeds supported by most newer computers. When set to NO, the parallel interface runs at the slower mode that is compatible with older computers. The user can also configure the ADVANCED FUNCTIONS item. The default setting, ON, allows for two-way parallel communications. The OFF mode disables the advanced functionality. The I/O is compatible with the bidirectional parallel interface standard. Expanded I/O The optional expanded I/O (EIO) card can be installed in the slots provided on the formatter. It provides automatic I/O switching between multiple computers or networks connected to the printer. HP Fast Infrared Receiver The optional HP Fast Infrared Receiver enables wireless printing from any iRDA-compliant portable device (such as a laptop computer) to the printer. The printing connection is maintained by positioning the sending infrared port within operating range. The connection can be blocked by objects such as a hand or paper, or by direct sunlight or any bright light shining into either infrared port. Flash Optional flash is available in 2 MB and 4 MB flash memory DIMMs for storing forms, fonts, and signatures. Hard-disk accessory The optional hard-disk accessory can be mounted in one of the EIO slots on the rear of the formatter. The optional EIO-based hard disk is used for creating multiple original prints (mopies) and storing forms, fonts, and signatures. CPU The HP LaserJet 4100 series printer formatter incorporates a 250 MHz RISC processor. EN Chapter 5 Theory of operation 105
