hp Indigo6900启动不了印刷?
 

各位大神，小弟用的是 hp Indigo6900，今天点击印刷，提示启动印刷会话错误请重试，后面再次重试还是一样的提示，请教各位大神这该如何解决？

First of all you should check the network connection between server and printing machine. Also check DNS resolving nothing sides from machine and from server.
Also in print controller check status of press should be connected.
And it will be great if you'll provide any screenshots to better understand the problem
