1.7 Cautions for Installation (IMPORTANT)
Please be sure to read the following cautions before using this product.
When you are going to install an upgraded version of the TEC printer driver, you must first uninstall the
older version in advance. For how to uninstall the printer driver, refer to Section 2.10 Uninstalling the
Printer Driver.
Failure to do so may cause unstable printing operations due to the influences of the files and registry
related to the old version remaining in the system. Follow the procedure in Section 2.10 Uninstalling
the Printer Driver, and the files and registry related to the printer driver will be deleted from the system.
Note: • This printer driver uses common program for the all applicable printer models.
• Even if the printer model is different, TPCL printer driver of different version cannot be used on the same PC.
• When installing TPCL printer driver for a new model on the PC in which the TPCL printer driver of different
version for another printer model has been already installed, the existing printer driver needs to be deleted.
When you are asked to select “Network” or “Local” in the Add Printer Wizard during the installation of the
printer driver, be sure to choose “Local”. Even when the printer will be used as a network printer, first
install the printer driver as a local printer, then specify a network path for the printer port later.
