The 7475A is still sold and the manuals are available:

  07475-90000  $100.00  Service
  07475-90001  $ 27.00  Programming
  07475-90002  $ 10.00  Operation and interconnection

The 7475A is an HP-GL plotter, and works with most HP-GL drivers.

The 7221C speaks a unique "compact binary" serial language.  Rather than
write a driver for it, I would suggest that you convert it to HP-GL
(effectively converting it to a 7220C) with the following 4-ROM kit:

HP part number 07221-00020, and has a U.S.list price of $80.00.
Contact your local HP Sales Office.
