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 version printers include the HP JetDirect Print Server with Ethernet 10Base-T, 10Base-2, and LocalTalk. Flash Flash is provided in optional 2 and 4 MB flash memory DIMMs for storage of forms, fonts, and signatures. Disk The optional 1.4 GB EIO-based hard drive is used for creating multiple original prints (mopies) and for storage of forms, fonts, and signatures. Local Talk I/O The printer implements AppleTalk networking protocol through LocalTalk hardware. The LocalTalk network cable (HP P/N 92215N) is connected through the EIO card. CPU The Formatter PCA incorporates a 100 MHz RISC processor. 5-14 Functional Information EN
