yes, that has almost nothing to do with the specific device

yes. You have to use a larger "left" margin (i.e. margin # 2),
see the 'mar' section in  help(par),
and also re-read the part on graphics in the "Introduction to R"

The following will look better {independently of the device,
postscript, X11, windows,...}:

  label <- expression(italic(A) == union(italic(H)[italic(i)],i==1,4))
  op <- par(mar = .1 + c(5,5,4,1))
  plot(1,1, xlab=label, ylab=label) 
  par(op)# to reset the graphics settings to the defaults
