We are printing labels which consist of 2 set of labels and we need to print both labels in sequence, everyting was working fine until we moved to new label printer.
If User 1 & User 2 send their Labels to the label printer at the same time we face the foolwing problem

Printout Sequence :-
1 - User 1 ---> First Label
2 - User 2 ---> First Label
3 - User 1 ---> Second Label
4 - User 2 ---> Second Label

We needed it to be in the correct order which is :-
Printout Sequence :-
1 - User 1 ---> First Label
2 - User 1 ---> Second Label
3 - User 2 ---> First Label
4 - User 2 ---> Second Label

that is happen randomly and based on if 2 or more users send their labels at the same time.

We are using VFP Versoin 7.0, Any Help
