Thermal Receipt Design Principles for Epson TM-T82

Bold is not decoration on a thermal printer — it is contrast control. A working guide to hierarchy, column budgets and what survives cheap paper.

Four ways to drive a TM-T82 — GDI driver, OPOS, ePOS-Print and raw bytes — compared on speed, control and failure modes, with working code for each.

The three ESC/POS features a POS actually depends on: the drawer kick pulse, cutting without slicing the total, and reading real-time printer status.

Why a network receipt printer stops printing, and how to prove where: port 9100 sessions, half-open sockets, timeouts and an idempotent print queue.

How Claude Code hooks run shell commands at lifecycle events to enforce formatting, block risky writes, and gate tasks on passing tests.

How Claude Code slash commands turn prompts you retype into reusable Markdown files with arguments, tool scoping, and live shell output.
