Input/output This section explains the printer input/output (I/O) capabilities. 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 on the control panel menu. (This item is found by navigating to the Configure Device menu, in the I/O menu, and Parallel Input.) 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 Advance 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 (HP Color LaserJet 4600 models) 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. USB 1.1 connector (HP Color LaserJet 4610n and 4650 models) The HP Color LaserJet 4650 models supports a USB 1.1 connector on the back of the printer. You must use an A-to-B type USB cable. Flash (HP Color LaserJet 4600 models) Optional flash is available in 4 MB flash memory DIMMs for storing forms, fonts, and signatures. Hard-disk accessory (HP Color LaserJet 4600 and 4650 models) 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 4600 models formatter incorporates a 400 MHz RISC processor. The formatter for the HP LaserJet 4610n and 4650 models incorporates a 533 MHz RISC processor.
