Problem: window.print() on the main page used A4 height (blank paper
after receipt), no RTL direction, and Tailwind styles leaked into print.
Solution — iframe isolation:
- lib/thermal-print.ts: builds a self-contained HTML document
(@page { size: 80mm auto; margin: 0 }, html { direction: rtl })
and fires it through a hidden off-screen <iframe>. The iframe
document contains only the receipt so height == content height.
- pos-slip-modal.tsx: Print button calls printThermal(buildThermalDocument())
instead of window.print(). Preview panel is unchanged (screen only).
- pos-receipt-print.css: updated @page + direction as fallback for any
remaining window.print() callers.
Works with USB driver (Atom A300) as default printer — OS print spooler
receives the job exactly as if it were any other document.

Meezi — Day 1 Quick Start
Step 1 — Copy these 4 files to your project root
.cursorrules ← AI rules for Cursor MEEZI_CURSOR_GUIDE.md ← Full development guide docker-compose.yml ← Local DB + Redis README.md ← This file
Step 2 — Start local services
docker-compose up -d
Step 3 — Create project structure
mkdir meezi && cd meezi git init
mkdir src web mobile cd src dotnet new sln -n Meezi dotnet new webapi -n Meezi.API --use-controllers dotnet new classlib -n Meezi.Core dotnet new classlib -n Meezi.Infrastructure dotnet new classlib -n Meezi.Shared dotnet sln add Meezi.API Meezi.Core Meezi.Infrastructure Meezi.Shared
cd ../web npx create-next-app@latest dashboard --typescript --tailwind --app
cd ../mobile flutter create meezi_app --org ir.meezi
Step 4 — Open in Cursor
cursor . (from the meezi/ root folder)
Step 5 — Paste this FIRST prompt in Cursor chat (Cmd+L)
Read .cursorrules and MEEZI_CURSOR_GUIDE.md completely. Then do Sprint 1 Week 1:
- Set up the .NET solution with proper references between projects
- Add all NuGet packages listed in the guide to each project
- Create the complete EF Core entity schema from the guide
- Set up AppDbContext with all DbSets
- Create TenantMiddleware and ITenantContext
- Set up Program.cs with full middleware pipeline
Cursor Chat Tips
Ask one sprint at a time
"Do Sprint 2: build the POS order APIs (menu, tables, orders)"
Reference specific sections
"Build the CRM endpoint from Step 10 of MEEZI_CURSOR_GUIDE.md"
Debug with context
"The order API returns 403. Check if TenantMiddleware is injecting CafeId correctly"
Generate Flutter screens
"Build the Flutter POS screen from Sprint 2 in the guide. RTL, Farsi, Riverpod state"
Useful Cursor Keyboard Shortcuts
Cmd+L → Open AI chat Cmd+K → Inline AI edit (select code first) Cmd+I → Composer (multi-file edits) Cmd+. → Quick fix / suggestion Tab → Accept autocomplete
