i want to explain it again that the problem is the select text option doesn't work after print to pdf. it freezes the text while the cursor is showing ....
Hi Afridi,
Sorry for the delay in response.
As you have mentioned above, select text option does not work when you use Print to PDF to create a PDF file and open the PDF in Adobe Acrobat Reader DC.
You have also mentioned that this happens to the PDF which is an image file or a scanned copy. Am I correct?
If the files are the Image or scan copy, you will not be able to select the text in the PDF.
As of the selection tool, it will select the part of that image file, not the text.
As you said " it freezes the text while the cursor is showing", it would be helpful if you can share the screenshot of the same.
To add the screenshot here, please use the insert icon provided in the reply window as shown below:

Once you click on this icon, you get a small window.
Click on Insert Image and then browse the location where you have saved the screenshot file.
Select the file and click on Open > Insert Image.
Also, if possible share some files on which you experience this issue.
You can share files using the steps mentioned here How to share a file using Adobe Document Cloud
Let us know if you have any question or need any help.
