# tallyflow-print Review
|
|
|
|
**Tech Stack:** Rust (Cargo)
|
|
|
|
## Purpose
|
|
Backend print service for TallyFlow Print. Handles label generation, RFID encoding, print job queuing/orchestration, and optional registration of printed assets into TallyFlow Core.
|
|
|
|
## Current Capabilities (post git pull - Jun 2026)
|
|
- Label config system with templates (simple_text, simple_text_2_5x1_25, datamatrix, etc.) and field_registry
|
|
- Parent/child label support
|
|
- Category names on tags
|
|
- orgsettings integration from TallyFlow
|
|
- Printing queue with enhanced orchestration and worker logic
|
|
- API endpoints for job submission and status
|
|
- Windows installation scripts and release support
|
|
- Updates to simple tag printing including RFID
|
|
|
|
## Key Components
|
|
- **api**: Main API service (port 8040)
|
|
- **orchestrator**: Proxies categories/zones and runs "print then register" flows (port 8041)
|
|
- **printing**: Core label generation and ZPL handling
|
|
- **worker**: Pulls jobs and sends to Zebra and compatible ZPL printers (raw TCP 9100)
|
|
- **label_configs**: Template definitions and manifest
|
|
- **web**: Web interface elements
|
|
|
|
## Architecture (from USER_GUIDE)
|
|
Operator → TallyFlow Print app → Print API → Print worker → Zebra printer
|
|
└── (optional) Orchestrator → TallyFlow Core
|
|
|
|
## Relevance
|
|
- Backend for the TallyFlow Print ingestion method (new tag assignment + optional data association)
|
|
- Works alongside tallyflow-print-ui (Flutter frontend)
|
|
- Supports all tag ingestion paths that involve printing/encoding
|

## Enhancement Suggestions (from clarification - Jun 2026)
|
|
**RFID Encoding Scope**
|
|
- Currently limited to EPC memory bank only
|
|
- Suggested: Add support for TID, User Memory banks
|
|
- Suggested: Add password protection / lock bits support
|
|
|
|
**Serialization & Numbering**
|
|
- Currently customer-managed via policy (different starting serials per printer instance)
|
|
- Suggested improvement: Allow per-printer serial number **range configuration** in Settings
|
|
- Range should **wrap around** when the end is reached
|
|
- Local serial tracking + increment already exists
|
|
|
|
**Multi-Printer & Orchestration**
|
|
- UI already supports multiple printers
|
|
- Core returns error on duplicate asset registration attempts (good safeguard)
|
|

## Roadmap / Integration Opportunities
|
|
- ~~**Mobile (Assets) integration** for Scan-and-Print~~ — **Shipped:** mobile can trigger print jobs (reprint, on-demand encoding during field scans or enrollment).
|
|
- **Edge integration** — Expose print job status/events and printer health to TallyFlow Edge for unified dashboards and alerts.
|
|
|
|
## Recent Changes (develop branch pull - July 2026)
|
|
**Major theme:** CSV import for batch printing, GS1 Sunrise dual-carrier retail tags, custom field registration, internal profile standardization.
|
|
|
|
**Key additions from develop:**
|
|
- Add import and database lookup via a CSV file for a list of parts and quantities to print (supports batch workflows).
|
|
- Initial support for retail GS1 Sunrise dual-carrier tags.
|
|
- Custom field registration support (bumped versions to 0.8.0 / 1.3.0).
|
|
- Add org custom fields to TallyFlow registration UI.
|
|
- Update profile name and id from 'simple' to 'internal'.
|
|
- Additional bug fixes and profile enhancements.
