# Barcode Labels

> Printing barcode labels on a Zebra ZD230T and what each label contains.

Every inventory item gets a printed barcode label. The label sticks to the physical equipment and is what your crew scans at Pick & Scan and Return & Inspect.

## Label format

JingjaiOps prints minimalist labels that contain only what's needed for scanning. Each label has:

* **Asset ID** as human-readable text (e.g., `CAM-001`)
* **Barcode** below the Asset ID (Code 128)

That's it. No logos, no item names, no rate. The Asset ID is the link to everything else — when the crew scans the barcode, JingjaiOps shows the full item details on screen.

This minimalist design is intentional:

* Labels stay readable even when small
* The same label format works for any item type
* If an item changes (different lens fitted, repaired, renamed), the label is still valid because the Asset ID never changes

## Hardware

JingjaiOps is tested with the **Zebra ZD230T** thermal transfer printer:

* Prints sharp 203 dpi labels
* Direct USB or Ethernet connection
* Uses 1.25" × 1" thermal transfer labels
* Sold widely in Thailand

Other Zebra ZPL-compatible printers will also work. The output is generated as a printable PDF, so any printer that handles 1.25" × 1" labels can be used in a pinch.

## Label size

The default label size is **1.25" × 1"** (32mm × 25mm). This fits most equipment — camera bodies, lens barrels, light fixtures, batteries, cases.

If you need larger labels for big equipment, JingjaiOps also supports **2" × 1"** and **3" × 1"** sizes. Set the size on a per-print basis when you click Print Label.

## Printing a label

### Single label

<Steps>
  <Step title="Open the item">
    From the Inventory list.
  </Step>

  <Step title="Click 'Print Label'">
    Top right of the item detail.
  </Step>

  <Step title="Choose label size">
    Defaults to 1.25" × 1".
  </Step>

  <Step title="Send to printer">
    The label PDF opens. Send to the Zebra printer like any other print job.
  </Step>
</Steps>

### Bulk printing

For new shipments where you need to print 50+ labels:

<Steps>
  <Step title="Open the inventory list">
    Filter to the items you just added (e.g., today's date).
  </Step>

  <Step title="Select multiple">
    Tick checkboxes next to the items.
  </Step>

  <Step title="Click 'Print Selected Labels'">
    A multi-page PDF opens, one label per page.
  </Step>

  <Step title="Send to printer">
    Print all pages. Labels print one after the other.
  </Step>
</Steps>

## Scanning the labels

Any USB or Bluetooth barcode scanner that emulates a keyboard works. Recommended scanners:

* **Zebra DS2208** — entry-level USB scanner, very reliable
* **Zebra DS3678** — heavy-duty, Bluetooth, holds up in a warehouse
* **Honeywell Voyager 1450g** — affordable USB option

You don't need a special "JingjaiOps scanner" — these scanners work because they type the scanned text into whatever field has focus, then press Enter.

## Replacing a damaged label

If a label gets torn, faded, or unreadable:

<Steps>
  <Step title="Open the item">
    Find the item in inventory by name or serial number.
  </Step>

  <Step title="Click 'Reprint Label'">
    Same as Print Label — produces a fresh label with the same Asset ID.
  </Step>

  <Step title="Stick the new label">
    Remove the old one and apply the replacement.
  </Step>
</Steps>

The Asset ID and barcode value are the same — old scan history continues to work without interruption.

## Label placement tips

* **Cameras and lenses**: stick on the side or bottom, away from screens and rotating rings.
* **Cases**: outside on a flat surface, ideally near the latch so it's visible when stacked.
* **Cables and small accessories**: wrap a label around with clear tape, or use a hang tag.
* **Lights**: on the body or stand mount, away from heat-prone areas.

For items that get a lot of contact (frequent in-and-out), use a **clear protective overlay** on top of the label to extend its life. JingjaiOps doesn't sell these — any 38mm × 28mm clear label sticker works.

<Tip>
  When you receive new gear, label everything before adding it to inventory in JingjaiOps. The first time you forget is the first time something goes out without a label and gets lost.
