Manually back up the printer driver on Windows 7

The company rented a new sharp AR-M450 all-in-one machine, the former provided by the official website Vista driver, but can be normal in Windows 7 use, but this time, I don't know why I used the same driver. All the printed data is garbled.

Fortunately, the available driver can be found through Windows Update.Program, The installation is also normal, .......

If multiple computers in the office are installed using Windows Update, it is estimated that there will be no 1 or 2 days of uncertainty (drivers installed in this way should know how slow the speed will be)

Find the following method to back up the driver on the computer that has installed the printer driver through Windows Update.

First, on the computer where the driver is already installed
Start --> Run (or directly "Win + R ") --> printui/s --> driver --> select the driver to be backed up --> Delete the driver and driver package --> In the displayed warning window, click "yes"

Now we can see the INF file name. Remember the file name (click Copy directly) and close the window for "Print Server properties ".

Enter the % WINDOWS % folder and use the obtained inf file name as the keyword to search.
% WINDOWS % \ System32 \ spool \ drivers \ w32x86 \ PCC
The folder contains a compressed package prefixed with the INF file name. This is the driver file we are looking for. decompress it and add the printer to other computers, select to install the driver from the disk, and then browse the corresponding folder.

P.s.
I'm on another 64-bit win 7 instance.
% WINDOWS % \ System32 \ spool \ drivers \
Folder, but not found a circle, then found through the search this compressed package has been decompressed, and is stored in
% WINDOWS % \ System32 \ driverstore \ filerepository
Folder (32-bit is actually under this folder)

The above method has only been tested on Windows 7. When I tested it on Windows 2003, I first did not run the printui command, but it can be run by the full name (the last word is case sensitive)
Rundll32 printui. dll, printuientry
But the problem comes again. On Windows 2003, when you click "delete", it will directly delete you... in addition to prompting whether to delete the file, other things are also available... so this method is useless at least on XP and 2003...
However, basically the old printers provide XP drivers...
