Input/Output

Parallel Interface

The Formatter PCA 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 may 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 for older computers. The user may 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 card can be installed in the slots provided on the Formatter PCA. It provides automatic I/O switching between multiple computers or networks connected to the printer. The network versions for the HP LaserJet 4000 series printers include LocalTalk and the HP JetDirect Multi-protocol Network Card with Ethernet/10Base-T and 10Base-2. The network versions for the

HP LaserJet 4050 series printers include the HP JetDirect Print Server with 10/100 Base TX.

HP Fast InfraRed Receiver

The HP Fast InfraRed Receiver enables wireless printing from any iRDA-compliant portable device (such as a laptop computer) to the HP LaserJet 4050, 4050 N, 4050 T, or 4050 TN printer.

The printing connection is maintained by positioning the sending infrared port within operating range. Note that the connection can be blocked by objects such as a hand, paper, direct sunlight, or any bright light shining into either infrared port.

Flash

Flash is provided in optional 2 MB and 4 MB flash memory DIMMs for storing forms, fonts, and signatures.
