Print issue

Hi priya5EB6,

Hope you are doing well.

Thank you for posting your query here. Please help me with few details to understand your issue better.

1. Which type of document are you printing?
2. Which printer are you using?
3. Was it working before?
4. Application version?
5. Make and model of your device?

We did try to replicate the behavior on our end, however, it is working fine. Make sure your application is updated. Do save your work then try to sign out and sign in back. Reboot your device. 
For Android Adobe Reader Mobile version: 21.3.0.17414 

Printing uses your device’s printing capabilities. You can set up a printer ahead of time or at the time of printing.

1. Open a PDF.

2. Tap on three dots...

3. Choose the print option. 

4. In the Printer Options dialog, select a printer.

5. Use the + and - buttons to set the number of copies to print.

6. Tap Print.
