Do samsung Laser printers enfore toner expiry dates?

As some anecdotal evidence, I have had a Samsung ML-1665 printer for about a year, and I am still on the original toner. I have never heard of printers expiring toner cartridges based on date. I know that some printers refuse to print on "low" toner cartridges with varying degrees of what they consider low, but sometimes a good fix for that is to just remove the toner and shake it a bit, which resets whatever mechanism it has for determining fullness.

After some Googling, it seems that the only evidence I can come up with for expiration dates on printers is for a small set of HP Inkjet Printers. I couldn't find any evidence of this occurring on any laser printers, or any other inkjet printers produced by other vendors.
