When I printed on the LJ4M I got the same results Andre did, i.e.,
412.0 426.0 940.0 (should be 412 426 428)
But ghostview shows
411.999 425.999 427.999 (should be 412 426 428)
Does this mean my LJ4M has the error? Does my ghostview have some other
error?
BTW, by printing the "Postscript Configuration Page" directly from the th
LJ4M, I see that the PostScript Version is 2011.110 . I could not find any
other identifiers that seemed relevant. What PS version do other LJ4M's
give?
