We started using scheduled pdf reports recently and noticed that the pdf generated is very wide. When digging through the code, It looks like the width of the headless chrome instance is set to a static value (1920px?) but it allows for a width parameter to be passed. However, I cannot find any way to pass that value from Zabbix Server to the Web Service. 
It would be nice to have that option either as a globally configurable value, or even better - in the report itself (by itself or as an override to a global value).
