Hi Tarasan,
We are sorry for the trouble. As described, the text of the same file is getting printed in different colors.
Is this a behavior with a particular PDF file or with all the PDFs? Please try printing a different PDF file and check. If its a file specific issue please share the file with us for testing. Upload the file on the document cloud (https://documentcloud.adobe.com/link/home/) generate the link and share the link.
Also please try to disable the protected view for testing. Please go to Adobe Acrobat / Reader DC (Mac), Edit (Windows) > Preferences > Enhanced Security > Disable the protected mode and Uncheck the Enhanced Security > Click OK and check.
Note: Please enable the security after testing.
You may also try to print as an image and see if that helps. Go to Print > Advanced > Print as image.
Let us know how it goes.
Regards
Amal
