Unable to bulk print - HTTP201 - half loaded pdf file

I was facing this issue and fixed it, the same way suggested. After that everything for a single document works fine, I mean when you enter the document and you goes to the print icon.

What I am trying to do is:

  1. in list view of salary slips
  2. select all
  3. actions
  4. print

I tried also to select one document in the list view-> actions->print and also the save.

it gives me a pdf that is half loaded,

these are the logs,
