As I said. I hadn't thought it through very much. I answered my own
question (at least this speculation.) a little while after the post.

O.K. That is what I wanted to know.

So I need to support both Pascal and Basic protocols. Is that what you
are saying? Let's say I only want to support only Pascal.(not that I am)
How many printers actually use the Basic Protocol. In the firmware
reference it states that the Pascal always needs a linefeed unless you do
blah blah. What about this? It is no big deal because you can turn them
on or off in the interface I have but just a question. I will look at the
Misc note #8. I thought I had them all at home anyway but I don't remember
this tech note given in the index. Of course, I reserve the right to be
absolutely wrong.
