Hello, you won't receive an answer with that less information...

What printer is it exactly? Why are you using MSComm-Object (which is a VB6 control as it seems) and not the SerialPort-Class? Does the printer even support different fonts? Can't you just install the/a driver and use PrintDocument?

Some background:
If you want to set the Font using SerialPort Communication you'll have to read the documentation of the device, or figure out what the control characters for that are. Most likely the printer is waiting for some non-printable character to switch to a different font.
