This problem occurs because Microsoft Report Server uses Active X, which is not supported by other browsers, including Google Chrome.   The following article gives some more information:

Workarounds: 
  1. Use Internet Explorer
  2. Use Google Chrome with the IE tab:  https://chrome.google.com/webstore/detail/ie-tab/hehijbfgiekmjfkfjpbkbammjbdenadd?hl=en-US.  Once installed, users should select the IE Tab when they want to print a report in Chrome.
  3. In Chrome, choose to save the report - then open it as a PDF, Word document, Excel file, etc. and print it from there.
