cg> Miscellaneous.PrintFiles LPT1 <FileName> ~
   prints via LPT1. 
Yes.  Parallel and serial ports all work 
for the HP LaserJet III here.  I use the 
parallel connection because it is faster.

cg> Miscellaneous.PrintFiles LPT1 <FileName> ~

I use that only with a dot matrix printer 
and set the font on the front panel.

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


cg> In which case ETH-oberon-S3 is sending such control chars ?

As I am aware Miscellaneous.PrintFiles sends 
only the plain text to the printer; no control 

cg> PSPrinter = {
 	Resolution = 300  <-- changed from 600 as 'test' no effect

That is for a PostScript printer.  No relevance 
to Miscellaneous.PrintFiles.

If your system is configured for a PostScript 
printer and you execute Desktops.PrintDoc the 
printer driver must compose a PostScript text.  
Resolution & etc. are used there.

cg> And how to increase the font size.

A simple driver for dot matrix printers
would be nice.  At least set the type-style 
and size.  For example <ESC>"et"<03X> sets 
the Courier type-face.  <ESC>"ev"<00X><C8X> 
sets 12 point size.  I've written no code.

In case anyone is interested, there is a 
programmer's manual for a Fujitsu DL3600  
here.  It specifies the Fujitsu original 
standard command set, DPL24C PLUS, and the 
emulation command sets for IBM Proprinter 
XL24, Epson LQ-2500 and Epson LQ-2550.
