initially it printed 2 lines of agarbled characters. then it said "processing info" on the printer and the data light would blink but nothign would print. now, the same thing is happening but the data light stays lit. i have tried EVERY suggestion from many different forums and nothing works. OS is XP. any ideas??

Networked? pull the NIC and do self tests. OK? Then check the driver used for the job. PCL or PS ? Sometimes when a NIC goes bad , it takes out the formatter too. If all self tests are ok, the it's the program, or driver.
