Working lp5250d last week, now refuses

to work.  The command prompt when issued creates the device, goes active, but the moment a stored print job in the queue is released the connection drops with a 'hardware error msg' on the qsysopr msgs and the connection is lost.   I can do a test print from printtool successfully and I can do a | to lpr -Plinuxoptra successfully, but I can no longer get a test print from the AS400.  The device will stay active if there is an alignment msg generated, until I answer the msg.   The only thing I did over the weekend was to try to make up some X desktop icons to call the lp5250d program from the desktop, but I"m back to trying the command line approach now, since none of them would work.   Thanks   Mike
