Update on 2015-12-11

I installed a bunch of Windows updates today and after that, the Lexmark E310 printer was no longer available. I tried the above procedure, but was unable to get past the “Devices and printers” window that tried to search for the printer but found nothing. I then searched in Windows for “add local printer” (or rather the equivalent in Swedish) and found another more useful dialog where there was an option “The printer I am looking for is not listed”. After that I could follow the steps above to get back the ability to print using this old laser printer.

Update on 2016-09-23

Today I got the “Windows 10 Anniversary Edition” update. It took a while to install (about on hour on a laptop and maybe 20 minutes on a more powerful machine). Again the printer stopped working and I tried to get it working using the above method (remove printer, add printer, printer is not listed etc), but after this I was not able to print. Instead I got some error message from Windows. I almost gave up, but then uninstalled the printer and turned it off and on. After that a test page that I had previously tried to print came out of the printer! I reinstalled the printer in the same way and after this it seems to be working. Phew.

Update on 2017-07-16

After getting the “Windows 10 Creator’s Update”, the printer disappeared again from the list of printers in Windows. The printer settings are no longer located under “Devices and Printers”, but under “Printers and Scanners” (why keep anything consistent when you can change it?). It was however reasonably straightforward to get the driver to work again using the guidelines above, but adapted to the new dialogs. Here is brief list of how to navigate the settings to get the printer working again:

1. Turn the printer on
2. Run Printers and Scanners
3. Add a printer or scanner
4. The printer that I want isn’t listed
5. Add a local printer or network printer with manual settings
6. Select the port USB001
7. Use the driver that is currently installed (Lexmark E312)
8. Change the printer name to Lexmark Optra E310
9. Select if you want to share it on the network
