Printer prints one extra page of rubbish

[Epikuros]

When I print something the printer usually prints an extra page with only
@N@N@N@N@X at the upper left corner.

The printer is brother HL-1040, I use cups and the driver is Foomatic/hl7x0
printer is in paraller port(/dev/lp0). I use lpr as the print command.

[edit: it was upper left corner, not upper right...]

It may only occur when I print only one page at a time.
