Disable right click file printing in windows?

Although you evidently have to remove these registry keys for individual file types, this is the most comprehensive list for it that I've found:

Windows Registry Editor Version 5.00

;--------
;-------- Remove "Print" from context menu for image files
;--------
[-HKEY_CLASSES_ROOT\SystemFileAssociations\image\shell\print]


;-------- 
;-------- Remove Print From common text-based files
;-------- 
[-HKEY_CLASSES_ROOT\SystemFileAssociations\text\shell\print]
[-HKEY_CLASSES_ROOT\batfile\shell\print]
[-HKEY_CLASSES_ROOT\cmdfile\shell\print]
[-HKEY_CLASSES_ROOT\docfile\shell\print]
[-HKEY_CLASSES_ROOT\fonfile\shell\print]
[-HKEY_CLASSES_ROOT\htmlfile\shell\print]
[-HKEY_CLASSES_ROOT\inffile\shell\print]
[-HKEY_CLASSES_ROOT\inifile\shell\print]
[-HKEY_CLASSES_ROOT\JSEFile\shell\print]
[-HKEY_CLASSES_ROOT\JSFile\shell\print]
[-HKEY_CLASSES_ROOT\MSInfo.Document\shell\print]
[-HKEY_CLASSES_ROOT\otffile\shell\print]
[-HKEY_CLASSES_ROOT\pfmfile\shell\print]
[-HKEY_CLASSES_ROOT\regfile\shell\print]
[-HKEY_CLASSES_ROOT\rtffile\shell\print]
[-HKEY_CLASSES_ROOT\ttcfile\shell\print]
[-HKEY_CLASSES_ROOT\ttffile\shell\print]
[-HKEY_CLASSES_ROOT\txtfile\shell\print]
[-HKEY_CLASSES_ROOT\VBEFile\shell\print]
[-HKEY_CLASSES_ROOT\VBSFile\shell\print]
[-HKEY_CLASSES_ROOT\Wordpad.Document.1\shell\print]
[-HKEY_CLASSES_ROOT\WPEDoc\shell\print]
[-HKEY_CLASSES_ROOT\WPSDoc\shell\print]
[-HKEY_CLASSES_ROOT\wrifile\shell\print]
[-HKEY_CLASSES_ROOT\WSFFile\shell\print]

;-------- 
;-------- Remove Print From Internet Shortcut
;-------- 
[-HKEY_LOCAL_MACHINE\SOFTWARE\Classes\InternetShortcut\shell\print]

;-------- 
;-------- Remove Print From Acrobat-/Foxit-registered .pdf files
;-------- 
[-HKEY_CLASSES_ROOT\AcroExch.Document.7\shell\print]
[-HKEY_CLASSES_ROOT\FoxitReader.Document\shell\print]

You can copy and paste this into a file of type .reg and double-click it to run it.

From here

Those kinds of options on the right-click menu are assigned per file type. If you're only interested in targeting a few file types, you can remove the print command from those file types.

For example, for PDF documents, go to HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.pdf and look at the default value. On my computer, the value is AcroExch.Document. So then you would go to HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AcroExch.Document\Shell and delete the print subkey.

You can disable Explorer's context menu with a GPO.
