The idea is that the WD-40 spreads unused ink into the ribbon's print area;
so, it will not work for restoring multi-Color ribbons. Since you are adding no
ink, this trick is good for only one or two 'restorations'.

009- Can anyone tell me how to connect a printer with a
"Centronics interface" to my Apple II?
The Centronics interface is the standard parallel interface for many
printers. To connect such a printer to an Apple II, you need a printer interface
card and cable. Since the cards were a popular item in the early 80's and were
produced by several different companies you should be able to get a good one
without too much trouble.
The cards turn up fairly often at swap meets, should be easy to find on
comp.sys.apple2.marketplace, and are still sold by regular A2 vendors. MC Price
Breakers (360-837-3042 Mon-Fri 9:30am-5:30pm Pacific Time) offers a "Full Text &
Graphic Interface" w/cable for Centronics type parallel printers for $29.95.

010- I bought a Grappler+ printer interface card at a
swap meet. Where can I get a cable? What is the pinout
for the cable?
The cable you need is the very common "Centronics cable". It is sold by
several Apple II vendors. The pinout is shown below:
