CWA HTML5 | Unable to print using Citrix PDF Printer
Article ID: CTX317949
Updated On:
Description
When trying to print from a published application, the users select the "Citrix PDF Printer" observe the message: "Getting PDF file...." (on the bottom right of the webpage) but do not see the "Continue print dialog" after which the document would open within a new tab.
Additionally, this behavior is observed after upgrade CWA for html5 2006 to newer versions like 2103
Resolution
Please add the below blob parameter inside the rw_act_insert_csp_nsg rewrite policy ->
add rewrite action rw_act_insert_csp_web insert_http_header Content-Security-Policy "\"default-src \'none\' ; form-action \'none\' ; frame-ancestors \'self\' ; base-url \'self\' ; script-src \'self\' ; style-src \'self\' ; img-src \'self\' *customer's cloud URL data: blob:\""
add rewrite action rw_act_insert_csp_web insert_http_header Content-Security-Policy "\"default-src \'none\' ; form-action \'none\' ; frame-ancestors \'self\' ; base-url \'self\' ; script-src \'self\' ; style-src \'self\' ; img-src \'self\' *customer's cloud URL data: blob:\""
Problem Cause
Rewrite policies for browser support were causing the issue with printing .
Upon reviewing the HTML5 logs, it was observed that after getting the print command, the print preview was not being generated because of content-security-policy. This security restriction was not allowing the print preview to come up.
