Ok Guys! I found the solution to the nasty “Problem communicating with the printer” AT LAAAST ! I have a lexmark x2480 and I recently upgraded to windows 7 ( I had the same problem with Vista earlier as well) so this problem has nothing to do with your operating system. The mistake I was making was that I first connected the cable and then began installing the setup.exe file. I never got the printer to work after that. Though strangely enough the scanner seems to work. I even enabled bidirectional port but it was no help. I tried unchecking the check box that said “save power….” in the usb port device I accessed using the device manger. No. Nothing works.
finally I found the answer. I uninstalled lemxark. I disabled the firewall. Then Disconnected the cable. Guys this is important you have to disconnect the cable and then only hit setup.exe. You must connect the cable only when the setup asks you to. And it works. I used the setup in my CD which I got when I bought the printer. Despite the fact that my OS is windows 7, 64 bit all works fine!
take care, hope this helps people like me who had to tear my hair apart for 3 hours+. VJ Koganti
