Assuming you mean that no background means that any background fill you 
have on the page isn't printed then...

Nothing is wrong I don't think - doing revBrowserPrint asks the browser 
to print - which means you'll get the same result as if you used the 
same browser outside of LiveCode and asked it to print. Typically the 
global style-sheet used to print is different than that which is used to 
display on the screen (I think at least).

The widget browser in LC8 uses the same underlying frameworks as 
revBrowser (although a largely rewritten code layer inbetween).

Printing widgets in LC8 relies on snapshotting them at the moment - 
which CEF doesn't allow in the mode you have to use to display it on the 
screen (with any degree of performance, at least). Indeed, this is 
something we need to still hook up for native widgets (the 'OnPaint' 
handler of widgets isn't called in the native case, so printing them 
will have no effect).
