Toner used in laser printers typically contains a mixture of fine plastic particles, carbon black for pigment, and various additives to improve flow and adherence. The plastic particles are usually made from styrene-acrylate or similar polymers that melt when heated to fuse the toner onto the paper. The carbon black provides the black color, while additives can enhance properties like charge control and fluidity. This combination allows for high-quality printing with sharp text and images.

Printers typically use the Print Spooler service, which manages print jobs sent to the printer. This service queues documents, allowing users to send multiple print requests without waiting for each one to finish. Additionally, printers may utilize other services like the Windows Driver Model (WDM) for communication and drivers specific to the printer model for compatibility and functionality.

Indelible ink is generally considered non-toxic and safe for use on the skin, as it is primarily composed of dyes and solvents that are not harmful in small amounts. However, ingestion or prolonged skin contact may cause irritation or allergic reactions in some individuals. It's always best to check the specific product's safety information and use it as intended. If there are concerns about exposure, consulting a medical professional is advisable.

The optimal humidity level for UV ink printing typically ranges between 40% and 60%. Maintaining this humidity ensures proper ink adhesion and curing, reducing issues like ink smudging or poor print quality. Excessive humidity can lead to problems with ink flow and drying, while too low humidity might cause static issues and affect the substrate. Monitoring and controlling the environment is essential for achieving consistent print results.
