B Printer memory and expansion
Overview
The printer has three dual inline memory module (DIMM) slots for upgrading with:

More printer memory — DIMMs (SDRAM) are available in 8, 16, 32, 64, 128, and 256 MB,
for a maximum of 416 MB.

Flash memory DIMMs (font DIMMs) — These DIMMs are available in 2, 4, 8, 12, and 16 MB.
Unlike standard printer memory, flash DIMMs can be used to store downloaded items, such
as fonts and forms, in the printer permanently, even when the printer is off.

Font DIMMs — These DIMMs allow the printer to print characters for traditional Chinese,
simplified Chinese, and Korean.

DIMM-based accessory fonts, macros, and patterns.

Other DIMM-based printer languages and printer options.
Note Single inline memory modules (SIMMs) used in previous HP LaserJet printers are not compatible
with the printer.
You might want to add more memory to the printer if you often print complex graphics, print
PostScript (PS) documents, or use many downloaded fonts. Added memory also gives you more
flexibility in supporting job-storage features, such as quick copying.
The printer has two EIO slots for expanding the printer capability with a mass storage device,
such as an optional hard disk for storing forms and fonts, and for certain job-storage functions.
The EIO slots are also used for adding a network card or a connectivity card for serial, USB, or
AppleTalk.
To find out how much memory is installed in the printer, or to find out what is installed in the EIO
slots, print a configuration page. (See
“Configuration page” on page 83 .)
