Squared Print Error

[Barneel]

Strange issue when printing a drawing. For some reason whenever I send this drawing to print the 'squared' symbols get replaced with either some overlapping numbers or the letter E.

 

Unfortunately I can't take a photo of the result but I'll provide an image of what I'm trying to print.

 

Plotting as a .pdf works fine (print preview also looks fine) and is the current work-around but it would be good to get a proper solution because it's likely these will be printed again from AC in the future and we'll forget and the client will get a stodgy drawing and I'll be sad.

 

Thanks

Did you use a different font for the squared symbol?

Same font. It's all Arial Unicode MS. Never had this problem before

I vaguely recall having a similar problem a long time ago with a custom font called "Fraction". I think it had something to do with Big Fonts but I am not 100% sure at the moment. I'll think on it some more.
