Print QR and barcode labels for library books

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

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

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

• 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.
