This may work because it uses different internal API. The client requests
are translated to NetWare protocol and send to mars. BTW I still haven't
public 63 bit POSIX locking patches for mars so you should not use CL53
or HB64 locks in such installations.

What GCC version you are talking about?
David's report suggests that code like:
proc main()
local hFile, cFile, cData
cFile := "PRN"
cData := "Printer test" + hb_osNewLine() + ;
Version() + hb_osNewLine() + ;
Os() + hb_osNewLine() + ;
DTOC( Date() ) + " " + Time() + hb_osNewLine() + ;
Chr( 12 )
if ( hFile := fopen( cFile, 2 ) ) != -1
? "Writting to", cFile
? "Bytes written:", fwrite( hFile, cData, len( cData ) ), ;
"from:", len( cData )
fclose( hFile )
else
? "Cannot open:", cFile
endif
return
does not work.
Does it work for you for printers connected to local computers?

Thank you very much. I missed it. I guess that it will work also for
local filesystems between processes.
best regards,
