Thermal Printing

A guides-first knowledge cluster explaining thermal printing technology in both of its major forms — direct thermal (heat-sensitive coated media) and thermal transfer (heated printhead melting ink from a ribbon onto media) — plus the consumables, printhead mechanics, media chemistry, control languages, and durability trade-offs behind receipts, shipping labels, barcodes, and wristbands. Coverage is vendor-neutral and standards-first, distinct from the two existing thermal stubs (glossary/thermal-printing and history/thermal-printing-history).
