Obviously there's something wrong with either the printer configuration or with
the way the lib etects it.

Nemo: please locate, in w32resources.ew, the line
vPrinterName = getDefaultPrinterName()
(should be at line 742),
add }}}
<eucode>puts(1,vPrinterName)</eucode>
{{{
 right after it, and tell us what got
displayed?
Also, at line 684 or close, locate
        rc = w32Func(xGetDefaultPrinter,{pBuffer,pNeeded})
and add a ?rc after that. The value displayed could be interesting.
