Do you have a Lexmark Computer? This extension for Lexmark Printer Sharing over the network. If your not using the network for your printer, block it and your printer should still run fine. (I use to have Lexmark but swtich to HP)

Some (or all ?) DELL printers are actually Lexmark and rebadged as DELL. I have the free “DELL 720” printer with my DELL PC and have blocked lexpps.exe both ways.
