Overview RAM Disk provides volatile temporary storage for the print data. Upon shut down of the device or loss of power the RAM Disk loses any data held in memory. The RAM Disk function meets the needs of customers with requirements to have no user print data written to mass storage, such as a hard disk, eMMC or SSD. With the installation of a supported HP DIMM, supported single-function printers can be configured to use the DIMM as RAM Disk.
