Slow printing with IBM AS 400 on xerox workcentre 7225 printer

Good morning all,

We have a printing problem on a Xerox workcentre 7225 printer, indeed, the prints pass normally and in real time on all microsoft applications, on the other hand on the AS 400, the prints are very slow;the file arrives at the printer and takes at least 5 minutes before printing.
What manipulation should we do to solve this problem!

Cordially.
