If you still have the old server available, download this tool.

Once you recreated on the new server, test to see if the printing speed is at all affected. If all works well, delete all the printers on the new server, delete any residual printer drivers and software that remain on the new server. Then recreate the image on the new server.
Sounds a little confusing, but read up on this tool. I used it many times, and it is especially important for us in our 30 printer environment. Use it in the future for any printer moving needs.
