All printers have some sort of volatile memory which is deleted if unplugged, much like the RAM in your computer, mobile phone, tablets etc.
Someone mentioned enterprise printers that might have long term memory for recovery in case of malfunction. That would be handled by a print server,
not by the printer itself, if at all.
If you're really concerned start looking into electronics and their respective labeling which will help you identify what each component does.
Static Ram Hard Drives (SSDs?) The closest thing I can think of is SRAM which has a subtype called Non-volatile SRAM, not really ideal for storing
significant amounts of data.
Sounds like rubbish to me to be honest.
