Lexpps.exe
(Lexmark)
Lexmark Printer Port Scanner. Background task which auto-loads with the rest of the printer drivers and which allows your Lexmark X or Z Series to be shared over a Windows peer-to-peer network using the conventional method of setting up a shared networked printer (without it, you will not be able to share the printer using the conventional Windows method).
Recommendation :
This task is a comprehensive nightmare. From preventing your PC from booting up, to interfering with your network card, to asking your Internet firewall for permission to install itself as a server application, to general PC instability, this task has everything to make you instantly return your Lexmark X or Z Series printer and go for something else, and some users have done so !! In order to regain your sanity the first thing to do is to rename LEXPPS.EXE to LEXPPS.EXE.OLD (do it in Safe Mode if you cannot boot your PC normally) this will ensure that this task never loads and will cure all the problems that it causes. If you need to network the printer over a peer to peer network, do not use the standard manner, instead install the printer as a local printer on the remote PC, and then go and change the port from a local port to the network share that the printer is known as.
