I am currently testing the appliance for deployment to replace our current iPrint Service on a physical server. I have set up 30 printers (the same number on our current iPrint server) for Airprint, App Print and Email printing, which all work fine. The problem comes when I install a printer from the Appliance on my Windows PC (iPrint 5.90), there is a very noticable delay from clicking print to the printer spitting it out...around 3-4 minutes. On our current iPrint server it is 15-30 seconds.

My question is, what should I be looking at to find out what is slowing down desktop printing?
