Unable to print pdf files in Acrobat Pro

You might try the following steps:

1- Disable Protected View- launch Acrobat>navigate to Edit>Preferences>Security (Enhanced)>select Off under Protected View and click OK. Then relaunch Acrobat and see if it works.

I would like to mention that disabling Protected View is for troubleshooting purpose only and not recommended, please turn the feature back on after finishing the troubleshooting.

2- Close Acrobat DC, go to C:\Users\your username\AppData\Roaming\Adobe\Acrobat\Acrobat version, move the entire [Acrobat version] folder to some other location like temp folder .

To view temp folder, press Windows+ R key on your keyboard, type temp in the run dialogue box then press enter.

If App data folder is not visible under your user name, launch Windows Explorer then click Organize in the top left corner of the screen>then click Folder and search options>under View>Hidden files and folders, click Show hidden files, folders and drives>then click Apply and OK, launch Acrobat again and check if its printing without any issue.

3- If step 3 doesn’t work, try to repair Acrobat installation, under Help menu>select Repair Installation.
