Epson 4800 & 9800 all of a sudden printing slow as molasses via network

My system was running perfectly with large print jobs taking at most 15 minutes to print. I moved from one house to another and now print jobs are taking 12 hours to complete. I have a PowerMac Dual processor 2GHz G5 running Leopard, connected to the network through a Netgear 8 port switch with a Uverse router/modem feeding that. Both Epson printers are connected to the same switch. Nothing else in the configuration has changed between the new house and the old one.

Ideas?
