Fix print icon.

[ehuss]

I accidentally missed that the logic was reversed in #1169.

@ehuss Sorry to bother you again.
As you mentioned in #1169 I pulled and checked but can still see the printer icon. Don't know I might be wrong.
Can you please check at your end once and confirm.
Thanks.

Hm, seems to work form me:

output.html.print.enable = true (default):

output.html.print.enable = false:

This is with d0deee9. Maybe check that you have the right version and the syntax in book.toml is correct?

Yes, really sorry to ask this.
I had my custom theme folder in book.toml. I disabled it and it worked well.
Thanks alot.
I think #1169 can be closed now.
