我在mac 的word 用中文文件，我必須要用標楷體(Biau kai)，但我有好多時間要把這些文件在windows下的word打開，再print。不過一開就成為細明體，我想有何方法可以在windows一開就是標楷體呢？多謝

make both mac and windows use the same font.

copy the font from one platform to another, most likely copy from windows to mac

I am no expert on this

but why you think post script won't work on mac?

then that's PC problem....

when I have your problem I simply solved by copy the font from pc to mac, not the vice versa

so no experience of fixing it on pc side

There is a way under Preference to "remap" the font between PC and Mac... It is very easy to do.  Say, the name of font may be different but you manual map it back
.

which preference? font book.app?
