Input/output The product receives print data primarily from the embedded HP Jetdirect print server. The product also has a USB 2.0 port for connecting directly to a computer. CPU The formatter incorporates a 533 MHz RISC processor. Memory The formatter system contains the product memory, which is divided into several components. This section describes each memory component. NOTE: If the product encounters a problem when managing available memory, a clearable warning message appears on the control panel. Hard disk The product comes standard with a 50 GB hard disk. The hard disk can permanently store fonts and forms. It can also be used for making multiple original prints and for job-storage features. Random-access memory The random-access memory (RAM) contains the page, I/O buffers, and the font storage area. It stores printing and font information received from the host system, and can also serve to temporarily store a full page of print-image data before the data is sent to the print engine. Memory capacity can be increased by adding a DIMM to the formatter. Note that adding memory might also increase the print speed for complex graphics. DIMM slot The DIMM slot can be used to add memory or fonts. Nonvolatile memory The product uses nonvolatile memory (NVRAM) to store I/O and print-environment-configuration information. The contents of NVRAM are retained when the product is turned off or disconnected. PJL overview The printer job language (PJL) is an integral part of configuration, in addition to the standard printer command language (PCL). With standard cabling, the product can use PJL to perform a variety of functions, such as these: ● Two-way communication with the host computer through a network connection or a USB connection. The product can inform the host about such things as the control-panel settings, and the control-panel settings can be changed from the host. ● Dynamic I/O switching. The product uses this switching to be configured with a host on each I/O. The product can receive data from more than one I/O simultaneously, until the I/O buffer is full. This can occur even when the product is offline. ENWW Formatter system 141
