Hello,
I have an Asus X750JN laptop with win 8.1 Pro 64-bit preinstalled.
Everything was running pretty smoothly until I installed a number of windows updates on May 16.
On that day, I could print using a Samsung CLP-365 colour laser printer; after the updates, I couldn't print at all.
I though the problme might be the followoing update:

Uninstalling & reinstalling didn't work, and I got error messages like this when trying a different samsung printer installation (after installation - in Devices and Printers):


However, trying other printers (eg a Lexmark B&W laser at home, and an HP B&W laser at work) gives similar error messages once installed.
The only printer that does work is an older HP Deskjet (multi-function- F2100).
Apart from this, the laptop is running fine.
I'm careful with security when online.
A lot of searching suggests one of the updates on the 16th is the cause of the trouble.
On the laptpo, there is a subdirectory within C:\Windows\System32\spool\drivers\x64\ created on the 16th May (cause of these problems??).
It has a long gibberish name, but even when running ‘cmd’ as Administrator, I still can’t access/delete these files.
Another issue could be in ‘services.msc’.
Name - ’Printer Extensions’ has a description of ‘<Failed to read description error code S>’
I'm relucant to try System Restore as I don't know how much it will delete. I can do it to 16th (before above problem updates) but this would see deleting of MS Office and other software.
Although I've got a partitioned HDD, I don't kow how many docs/photos/emails/etc in a seprate partition to that for Windows would be removed as well with System Restore - it seems too risky.
I've got the IT support company at work to check this out using remote access software and even they are stumped.
I'm the only user and have adminstrative rights for the laptop.
I'm just about pulling my hair out with this one.
Thanks,
John
