MJX Library prints a sticker for every numbered copy: a QR code for phone cameras and a barcode for barcode guns, with the copy's number, the title and your library's name. Stick it inside the cover and every issue and return becomes one scan.

## How to open the label sheet

> [!PATH] Apps › MJX Library › Books & lending › Labels

You can also open one book and press **Print labels for this book** for only its copies. Labels are for the owner and admins; anyone else is sent back to Books.

## Steps to number copies that have none

The page tells you how many copies have no number yet ("*12* copies have no number yet, so they get no label").

1. Type **Starts with (optional)** — for example `A-`.
2. Type the **First number** — for example `101`, or `0001` to keep four digits.
3. Press [[Number them]].

Copies are numbered in shelf order (by title). MJX Library never invents numbers on its own — you choose how they start.

## Steps to print labels

1. Under **Which printer do you have?** pick one:
   - **A4 sticker sheet** — any home or office printer, 24 stickers a sheet.
   - **Sticker printer (roll)** — TSC, Zebra, Xprinter, Godex, Brother… on this computer.
   - **Pocket / Bluetooth printer** — prints from its own phone app.
2. For a roll or pocket printer, pick the **Sticker size on your roll** (see the table), or **Another size — type it** and enter **Width (mm)** and **Height (mm)**.
3. On an A4 sheet you have partly used, set **Stickers already used on the first sheet**.
4. Press [[Print]] — or [[Download PDF]] (the main button for pocket printers).

### Sticker sizes offered

| Size | Notes |
|---|---|
| A4 sheet of 24 stickers | Any printer |
| 50 × 25 mm | The usual sticker roll |
| 38 × 25 mm | |
| 40 × 30 mm | |
| 2 × 1 inch | |
| 50 × 30 mm | Pocket printers |
| 60 × 40 mm | |
| 30 × 15 mm | Small pocket printers — QR only, no barcode |
| Another size | Type width and height in millimetres |

If a number is too long, or the sticker too small, for a barcode a gun can read, that sticker gets the QR only and the page tells you.

## Printer settings that matter

> [!IMPORTANT]
> **A4:** in the print box choose **Scale: 100%** (or "Actual size") and **Margins: None**. "Fit to page" shrinks the stickers off their places.

- **Roll printer:** choose your sticker printer, then **Margins: None** and **Scale: 100%**. Each sticker is its own page. If the printer asks for a paper size, make the same size once in its settings (Printer properties › Paper / Stock).
- **Pocket printer on a phone:** press [[Download PDF]], then **Share** › your printer's app. Choose the same sticker size in the printer's app.

## Printing from the MJX Library app

In the app, tap **More** and, under **Desk**, **Print labels** (or open a book and press [[Print labels]]). Choose **All your books** or one book, then **Your printer and sticker size**. Press [[Share as PDF]] or [[Share as pictures]] and pick your printer's app — most take the PDF, some only pictures. The app can number copies too: **Starts with (optional), e.g. A-** and **First number, e.g. 101**, then [[Number them]]. Already-used numbers are refused, never skipped.

> [!TIP]
> A big catalogue prints in pages. If the page says "Only the first … are on this page", print them, then pick one book at a time for the rest.

## Who can use it?

Owner and admin, on every plan.

## Questions people ask

### What is printed on each label?

The copy's accession number as a QR code (for a phone camera) and a barcode (for a barcode gun), with the number in large print, the book's title and your library's name.

### Which printers work?

Any home or office printer with A4 sticker sheets of 24, a roll sticker printer on a computer (TSC, Zebra, Xprinter, Godex, Brother and others), or a pocket Bluetooth printer through its own phone app.

### Why does a copy have no label?

A label carries the copy's number. A copy with no accession number gets no label until you number it.

### My stickers print shrunk or out of place. Why?

The print box was set to Fit to page. Choose Scale 100% (or Actual size) and Margins None.

### I have used some stickers on an A4 sheet. Can I use the rest?

Yes. Set Stickers already used on the first sheet and printing starts after them.
