摘要
An example of a computer-readable medium storing machine-readable instructions. When executed, the machine-readable instructions may cause a processor to control a laser to print a test pattern. The test pattern may be scanned to determine visibility of pixels. The power of a laser may be adjusted based on the visibilities to print a security pixel.
