Fix some issues with the Zebra ZPL printer driver (Issue #4898)

- Move "delete graphic" command after "end format" command since some older
  printers seem to have bugs with that.
- Add "print width" command so that label is properly centered.
- Add "inverted orientation" command so that labels are properly oriented
  (leading-edge == top)
