USB hosts
The product includes USB hosts for USB flash drive and wireless communication control.
Memory
If the product encounters a problem when managing available memory, a clearable warning message
appears on the control panel.
Flash memory
NOR: Stores microprocessor control programs and internal character sets (fonts).
NAND: Stores fax memory and driver installation software.
Random access memory
All models come with 192 MB of memory installed. The formatter has 256MB NAND Flash.
Nonvolatile memory
The product uses nonvolatile memory (NVRAM) to store I/O and information about the print environment
configuration. The contents of NVRAM are retained when the product is turned off or disconnected.
Memory Enhancement technology
The HP Memory Enhancement technology (MEt) effectively doubles the standard memory through a variety
of font- and data-compression methods.
NOTE: The MEt is available only in PCL mode; it is not functional when printing in PS mode.
Wireless radio
Wireless products contain a wireless card to enable 802.11b/g/n wireless communication.
PJL overview
Printer job language (PJL) is an integral part of configuration, in addition to the standard printer command
language (PCL). With standard cabling, use PJL to perform a variety of functions.
●
Dynamic I/O switching. The product can be configured with a host on each I/O by using dynamic I/O
switching. Even when the product is offline, it can receive data from more than oneI/O simultaneously,
until the I/O buffer is full.
●
Context-sensitive switching. The product can automatically recognize the personality (PS or PCL) of
each job and configure itself in that personality.
●
Isolation of print environment settings from one print job to the next. For example, if a print job is sent
to the product in landscape mode, the subsequent print jobs are printed in landscape mode only if they
are formatted for it.
