The log shows that the printer does not support high speed, no matter what HP says. The problem is in the printer, not in your computer. By the way, does HP actually say "full speed"? That is 12 Mb/s. 480 Mb/s is known as "high speed". Alan Stern ------------------------------------------------------------------------- Using Tomcat but need to do more?
