In order to allow PP-8902 to successfully detect what interface you are
using to transmit data, make sure ONLY ONE type of interface cable is
connected to avoid confusion. Also, reboot PP-8902 after you change
the interface cable for the printer, which enables the printer to
automatically re-detect the type of interface which is currently used.

Cleaning
Cleaning the Printer Case
Before cleaning the printer case, be sure to power off the printer, and wipe the
dirt off the printer case with a soft wiping cloth we provide.
Do NOT clean the product with alcohol, benzene, thinner, or
other such solvents. Doing so may damage or break the parts
made of plastic and rubber.
Cleaning the Thermal Head and the Platen Roller
In most cases, it is strongly recommended to regularly cleaning the thermal
head to maintain receipt print quality (about once every 3 months). While
using the printer, always ensure that dust particles are removed from paper
rolls and the gear by using the platen roller with a cotton swab moistened with
water. Then, power on the printer only after water has dried.
After printing, the thermal head and its surroundings
can be overheated. Make sure that it is completely
cooled down before cleaning it.
Do not damage the thermal head with your fingers or
any other hard object.
