What Is Variable Data Printing
Variable data printing means printing different information on each item. For example, printing a unique serial number on every box, or a different batch number on each pallet.
Without automation: Operator types each number manually. Slow. Error prone.
With a scan engine: Operator scans a barcode. The printer reads the data and prints it. Fast. Accurate. No typing.
How It Works
Operator picks up handheld printer with embedded scan engine
Scans a QR code or Data Matrix from a work order, product label, or shipping document
Scan engine reads the variable data (batch number, serial number, date code)
Printer prints the data directly onto the product or box
Operator moves to next item, scans next code, prints next data
Each scan triggers a print. Each print can be different.
What Variable Data Can Be Printed
| Data Type | Example | Source Code |
|---|---|---|
| Batch number | BATCH 2405A | QR code on work order |
| Serial number | SN: 001234 | Data Matrix on product label |
| Lot number | LOT 89C | Code 128 on pallet tag |
| Expiration date | EXP 2026 12 31 | QR code on shipping doc |
| Order number | PO 45678 | PDF417 on invoice |
| Customer code | CUST A876 | QR code on packing slip |
Real World Example
Handheld inkjet printer marking serial numbers on electronics boxes:
Operator scans QR code on each box (box contains serial number)
Scan engine reads the serial number
Printer prints the serial number directly on the box
Each box gets its own unique serial number
100 boxes = 100 scans + 100 prints. No typing. No wrong numbers.
