It is an Epson Photo 700, but I also hooked up a Brother HL-720 and had the same problem. I also swapped proscessors (swapped my P4 1.6 with a P4 1.4), it still happened. I swapped my mobo (Asus P4B266 with a Asus P4T-E) it still happened. I tried both proscessors in all combonations with both motherboards, The P4T-E had 512 megs rambus memmory, the P2B266 has 512 megs of DDR. I reformatted the HD & installed nothing but WIN XP, It still happens! I'm almost at the end of my rope. I hate the thought of this, but I think the only way to get around this is to reinstall ME or 98se. Maybe a print server plugged into my hub?
