my lexmark E238 connects to 2 pcs - 1 via reg cable other via usb -- this config worked before

cntrl/prntrs/faxes shows 2 pc's connected
pc's hardware profile shows same

power is on; toner indicator NOT on; paper tray full

when attempt to print... prntr icon appears... cntrl/prntr/faxes shows print job but no printing

i never touched the drivers - and frankly i dont know which one to download at lexmark.com -- way too many and varied for windows...!!??

help! i need this to run a business, thanx
