    The ImageWriter II/L cannot add more memory, it's stuck with the
built-in 24K and no more. You can install an internal memory card but
as far as I know, it'll just ignore it and you'll still have only 24K.

    The older models came with only 2K built-in but can accept more 
memory. Apple sold a 32K RAM option card you could plug into the
older printer, so did Sequential Systems with their Q-Buff card. No
big loss (24K vs 32K), except when you consider the MegaBuff
which added a full 1 Megabyte to the printer which the II/L, again,
would ignore.

ps - A minor correction. The II/L came out in early 1990 actually.
