Right clicking "Print PDF" does not print all selected

[Kelli3902464057cz]

I have multiple users on Windows 10 who use the windows explorer, right click print option to print their PDF's.  

They have Adobe Reader as their default PDF reader and have selected their own shared copier as default, not allowing Windows to set the default printer.  We are printing to a Canon iR-ADV 6860 using the Canon Generic Plus PLC6 driver.

When they select multiple files (2-50 files) they never get them all to print.  They get a random number to print and it is not consistant, some times they'll have 3 or 14 or 22 print or any other number of files to print.

Has anyone else seen this or know how to fix it?  It's beyond a pain for the users who print on the daily.

I have updated both Adobe reader and our print driver to the latest versions.  It used to work before we upgraded our copier but the vendor does not think it's a "them" issue.

Hi,

I had the same issue with a machine, FOXIT PDF reader worked so I knew it was a Adobe issue.

Found the below on another post and this resolved the issue for me.

Seems like with this ticked it couldn't open all the files to then print them.

How to FIX: Acrobat Reader Can't Print PDF files in Windows 10 2004.

Method 1. Disable the Protected Mode in Acrobat Reader.

For an unknown reason, the printing problem in Acrobat Reader may appear, if the "Protected Mode at startup" setting is enabled. To turn off the "Protected Mode at startup":

1. Open the Acrobat Reader DC program and from the Edit menu choose Preferences.

2. Select Security (Enhanced) on the left pane and then uncheck the Enable Protected Mode at startup checkbox at the right.

3. At the pop-up window, ask Yes.

4. Click OK to close the Preferences settings.
5. Close and re-open the Acrobat Reader application and try to print a PDF file

Thank you so much!  I was able to have 2 users test this and it seems to be the issue.
