PDF error: unknown operator

Hello Dolibarr and all users,
I have a problem when I print the invoice pdf directly, only on network printers, not USB ones.
in the office we only have 2 black and white USB printers, against 10 network color printers.
The version of Dolibarr we are using is v16.x, before we used v14.x but we had no printing problems.
HELP ME. thank you
