Windows XP prints queued datas in bad order

I have two computers connected to LAN network. One runs Windows XP and
shares its printer to others on network. Second one runs Windows 98 second
edition and uses printer from Windows XP. When I print at Windows 98
computer from MSDOS application using port LPT1 (which is captured to
\\winxp\printer), printing job is usually splitted into 3 (sometime more
then 3) parts. On printer then output looks as follow - first it is printed
3.-rd part, next is printed part 2. and 1.-st part is sometime printed,
sometime not, but everytime on the end.

I tried to switch out "print spooled documents first" in properties of the
printer on Windows XP, but it did'nt help. What may be wrong?

Thank You in advance
