[Oberon] Update: If/why no Centronics print capability ?

Miscellaneous.PrintFiles LPT1 <FileName> ~
   prints via LPT1.  The line terminators must be appropriate.

But the font [on this simple dot matrix printer] is smaller than
when driven by linux or DOS.

I've understood that such simple printers have a default size/font,
unless special control-chars are sent initially ?

In which case ETH-oberon-S3 is sending such control chars ?
I use ET.StoreAscii *   on the text file.   And Hex.Open ^  shows that
the file has no extra leading characters.

So I'm guessing that the parameters in Oberon.Text are setting the
size.   I read:

How would I know if/what values are valid.
And how to increase the font size.

Thanks for info,
