I think I've found a kind of answer:

After changing default printer from network to a local one I've
achieved result 0.7 s. Anyway for a first time setting bold takes 0.6
s, second time - 0.3 s.

Anyway is there any way to increase speed without this printers issue?
Or how can it be avoided programmatically without asking end-user to
use a correct printer?

Thanx,
