I have an HP deskjet connected to my usb and am connected to another HP lasrjet through our Lan. I cant print fine through the network. But when I print to my local printer and then try to print to my network printer my application stops responding (mail excel word whatever). I must do an add printer and add the network print back again. I had this happen at another place I worked. Is it something with the software for the deskjet that won't release??
