5. Restart the printer: If the printer font is not displayed, you can try to turn it off and on again, and then restart the computer. Then try printing the file again to see if it can solve the problem.
In short, if the printer font is not displayed, you can try the above solutions to determine where the problem lies and find the best solution.
