If you have the PX-870A, PX-880SA, or the PX-B320SA and can't find where to print a Lightscribe label, you may need to install the labeling software from the original Roxio Creator 10 CE installation disc.Whether you have Roxio installed or not, just insert the disc and click on the prompts to install the software.
When you get to the screen above, select CUSTOM install and in the list of components, make sure there is a checkmark next to Roxio Express Labler 3.
Once the installation is complete, you may also need to download and install the latest version of the Lightscribe System Software. The update can be obtained directly from the official Lightscribe website or by clicking on the link below. A reboot may be required to complete the installation.
Once all the necessary software is installed, simply open up Roxio Creator 10 CE and then click on the TOOLS menu on the left hand side. Click on LABEL DISC and the Roxio Express Labler software will open.
