I haven't done much of this, but you should be on the right track with IupPlotPaintTo().

You don't have an imImage with IupPlot, so let's rip all that out. Try this (untested):

function item_print_action_cb(Ihandle /*item_print*/) 
cdCanvan print_canvas = cdCreateCanvas(CD_PRINTER, "myplot -d") 
    if print_canvas!=NULL then 
        IupPlotPaintTo(plot, print_canvas) 
        IupSetAttribute(plot,"REDRAW",NULL) 
        cdKillCanvas(print_canvas) 
    end if 
    return IUP_DEFAULT 
end function 

If it does not work, and I find time tomorrow, I'll have a bash at adding this to the plot demo.
