i want to link simsun.ttc to my font and i need the button next to print on the front page of a font to be enabled.
I’m not sure what you mean by “link simsun.ttc to my font”, or which button next to Print you are referring to.
Could you please post a screenshot showing the button, and explain what you want to achieve with SimSun.ttc and your font? Then we can better understand what you are trying to do.
