If you are refering to print speed, from the label format, press F5 to bring up the LABEL & SETUP PROPERTIES. Click on LABEL OPTIONS and print speed will be the first choice.
If you are refering to how fast data is sent to the printer, then that depends on the connection to the PC and whether you are using true-type fonts or not.
