Practical guides from the work we do on real production lines: reading printed characters with OCR, grading barcode print quality, and getting data out of handheld devices and PDAs.
Every guide is written from field experience, not a spec sheet. If a limitation is real, we say so.

OCR guides
Reading printed text — serials, lot codes, dates — where a barcode reader has nothing to say.
| Guide | What you’ll learn |
|---|---|
| Scanner-OCR: Add OCR to Your Barcode Scanner | How to turn a handheld scanner into an OCR reader, offline, on the PC you already have |
| Fixed-Mount OCR: Read Characters and Grade Quality on the Line | Unattended, IO-triggered capture with content and quality from one scan |
| Android-OCR: On-Device OCR for Android PDAs | Turning a PDA into an OCR terminal — scan key, broadcast or floating button |
| Web OCR: Test On-Device OCR in Your Browser, Free | Run OCR on an image in the browser and compare model tiers |
| How One OCR Framework Powers Three Product Lines | Why scanner, fixed-mount and Android share one engine — and what that buys you |
Barcode and print quality guides
A code that scans is not a code that passes.
| Guide | What you’ll learn |
|---|---|
| Barcode Quality Grading: ISO 15416 / 15415 in Software | What ISO grading actually measures, and where a software grader honestly fits |
| Label Inspection | Catching a missing dot or a broken border before it ships — template comparison explained |
Device and tooling guides
| Guide | What you’ll learn |
|---|---|
| AI-ADB: Control Any Android Device From Your Browser | Files, apps, logcat and screen mirroring over a USB cable — no drivers, no install |
| Custom Firmware for Handheld Scanners: Format and Decode Plugins | Making a scanner do more than decode — parsing and formatting at the edge |
Reference
Quick-lookup material lives separately. Reference tables and datasheets are on the way.
