Easy to check. Make some file with bytes in the rage 160..255, then
do
chcp 1252
copy this-file LPT1
chcp 1251
copy this-file LPT1
chcp 866
copy this-file LPT1
(May be interesting if FF-between-jobs-is-required...)

Maybe. But what I was reacting on was your initial claim similar to
"ALL one needs for printing under Win* is to know a name of a pipe".
In my book, "printing ASCII" is hardly equivalent to "printing".

??? IIRC, now we are discussing not the printer, but the pipe...
Anyway, consider these questions as concerning a pipe. (Yet another
question is how to *force* a sequence of bytes to be recognized as
TEXT [as opposed to MetaFile or RAW_PRINTER_COMMANDS].)

> Translated initially from plain text in whatever encoding we sent it,
"Plain text" is not a description of a format. And I do not know what
is "whatever encoding"; you have either one encoding, or some other;
obviously the pipe can't recognize both. But these question are
already asked in two chunks above...

According to the MS links you posted, I'm right; this pipes accepts
RAW_PRINTER_COMMANDS. How it distinguishes it from "plain text"
(which it supports "too", whatever it means) is not documented...

This has nothing to do with Unicode. Only if you print ASCII only you
can forget about encodings; but again, in many situations even ASCII
is ambiguous - if UCS* are entring the question. [I hope the pipe
does not try to autodetect UCSle...]
Hope htis helps,
