"printer colors" /and/ xaralx ?

I am a Linux person, and therefore rely on the XaraLX branch...
and I should say, I have, some months ago, downloaded and
used the CMYK color space plugin or file... now for my question,
relating to these.

At the library... all windows type machines... I can download
the Xtreme-Pro 30-day version, and while this may be limited,
I have found a really helpful function in this... by clicking one
of the menus, one can use "printer colors"... and, somewhat
like the older CMYK plugin, its now possible to very closely
approximate what the printer will output (we have a CMYK
laser printer here). (puff...puff...puff... sorry about this long
intro :-) Now the question...Im wondering if there is anything
available, along the lines of that CMYK color space add-on,
in which one can work directly in "printer color"... Im not sure
what the difference is, but to me it is quite noticeable, between
CMYK and "printer color".

So... to condense the question... is anything available presently
for xaralx users which duplicates this "printer color" option seen
in Xtreme-Pro ? Thanks for reading, and happy XARA-ing to all !
