All our printers print with iPrint.
We have about 10 different printers.
And one of the an hp4250 does not print the output correctly when we dive them the command to sort the print.

I installed the actual print driver (PS) but all machines with this printer as printer can not sort the print.
I searched the web and found an old information at Microsoft Website.
But it seams, that this is not applicable for us.
Our WS are working with WINXP SP3.
