24 HP LaserJet 5P Printer Service Supplement New Product Features Interface Connections Your HP LaserJet 5P or 5MP printer supports the following interfaces (see Figure 11): • Two IEEE-1284–compliant parallel ports at the back of the printer—one large B-type and one small C-type. • One LocalTalk port at the back of the printer. • One IrDA-compliant infrared port at the front of the printer. Figure 11 HP LaserJet 5P/5MP Printer Interface Connections 1. LocalTalk cable and connectors. 2. IEEE-1284 parallel cable and large (B-type) printer connector. 3. IEEE-1284 parallel cable and small (C-type) printer connector. (The cable wil be stamped as IEEE-1284 compatible. 4. Host PC connector (A-type) (in the future C-type connectors may also be available on host PCs). C a u t i o n Make sure that all power and interface cables on your printer and host computer are properly grounded and in compliance with local electrical codes. 25 HP LaserJet 5P Printer Service Supplement New Product Features The Parallel Printer Interfaces These interfaces are compliant with IEEE-1284 specifications for "Compatibility Mode” and “Nibble Mode” or “HP Bi-tronics”. To use advanced interface functions, such as bi-directional communication, the parallel port on your host PC must also be IEEE-1284 "Nibble Mode" compatible. The small “C” connector offers IEEE-1284 II (level 2) electrical interfacing, i.e. support for cables up to 10 meter length. The large "B" connector supports standard cable lengths up to 3 meters. The parallel interfaces can operate at speeds of up to 2 MBytes per second. Use a high-quality, shielded IEEE-1284 compliant parallel interface cable to insure best performance and support of advanced interface functions such as bi-directional communication. Compliant cables are marked with “IEEE-1284" on the cable. Applications such as the Remote Control Panel, Status Monitor, or the Status Window use the printer’s parallel interface to send status information back to the computer (bi-directional communication). This requires a direct connection from the computer to the printer via a local parallel port (for example, LPT1:, LPT2:). These applications may not work through a network or a switching device. Connecting to Networks and Switchboxes Most devices connected between the printer and the host computer prevent the printer from sending data back to the computer. Therefore, the Remote Control Panel, Status Monitor, and Status Window may not work with networks, most hardware print spoolers, some software print spoolers, and some switchboxes. Newer sharing devices are available that fully support status feedback. Check with your supplier on support for bi-directional communication. Automatic I/O Switching The printer automatically switches between all interfaces (parallel, infrared, and LocalTalk) when multiple users share the printer. 26 HP LaserJet 5P Printer Service Supplement New Product Features Resource Saving Resource Saving gives the printer the ability to save certain entities such as permanent soft fonts, macros, symbol sets and user-defined graphics patterns when the printer changes personalities, resolutions or page protect modes. For example, if a user switches the printer from PCL mode to PostScript mode, all PCL soft fonts and macros are lost. With resource saving, the HP LaserJet 5P/5MP printer can retain these in memory. When the user switches back to PCL from PostScript all of the PCL entities would still be resident in the HP LaserJet 5P/5MP printer. Resource Saving can be changed via software, but can only be accessed when the printer has the PostScript language installed and a minimum memory configuration of 7 MB. Resource Saving can be set via software for one of three modes, AUTO (default), ON, and OFF. Auto configuration sets the Resource Saving for PCL and Postscript to a minimum value (400 KBytes) for each personality. Setting Resource Saving to ON allows the user to determine how much printer memory will be used for Resource Saving for the PCL personality and the Postscript personality. The memory can be allocated in 100 KBytes increments. For example, if the user sets the Resource Saving memory size to 200 KBytes, a total of 400 KBytes of memory will be assigned to Resource Saving. 200 KBytes of memory will be used for Postscript Resource Saving and 200 KBytes of memory will be used for PCL Resource Saving. Turning Resource Saving OFF disables the Resource Saving function and no memory is allocated to Resource Saving. 27 HP LaserJet 5P Printer Service Supplement New Product Features I/O Buffering I/O buffering allows the user to allocate printer memory to hold the job while it prints, freeing up the host system sooner, like a print spooler. The standard printer has approximately 10 KBytes of memory allocated to I/O buffering and an additional 100 KBytes of memory is assigned to I/O buffering for each MBytes of memory added to the printer. If the printer has a minimum of 6 MBytes of memory installed, the I/O buffer size can also be adjusted via software. Three settings exist for the I/O buffer; AUTO (default), ON, and OFF. AUTO sets the printer’s I/O buffer to a minimum value that is determined by the total amount of memory that is resident in the printer. Setting I/O buffering to ON allows the user to set the I/O buffer size
