HP LaserJet 4345 Multifunction Printer series - Manual (Page 286)

Memory overview
The MFP has two double data rate (DDR) DIMM slots to provide more MFP memory. DDR
DIMMs are available in 64, 128, and 256 MB, and can be combined in the MFP for a
maximum of 512 MB.
The MFP has two flash memory slots to provide the following features:
● Flash memory cards, available in 16, 32, and 64 MB. Unlike standard MFP memory,
flash memory cards can be used to permanently store downloaded items in the MFP,
even when the MFP is off. The MFP supports Type 1 and Type 2 flash memory.
● To add flash-based memory accessory fonts, macros, and patterns, use the appropriate
DDR DIMM.
● To add other flash-based printer languages and MFP options, use the appropriate DDR
DIMM.
Note Single in line memory modules (SIMMs) that are used on previous HP LaserJet products are
not compatible with this MFP.
