Yes. Your Postscript says to use an 8.5"x11" page and then to draw the
barcode at the bottom left of that. If you save this to a file and view
it with evince, ghostview or whatever, you'll see that.
So, what you're trying to do is place an 8.5"x11" page at the bottom/top
of a letter sheet. That's not really going to move the contents of the
page.
So, either print the barcode to a smaller sheet (so your postscript page
is smaller) and then locate that on your sheet of letter paper, or keep
the postscript page the same as your target, and locate the barcode
elsewhere in that.
