Printing Barcode Tags

JewelTrak prints barcode tags for every inventory type (jewelry, watches, diamonds, colored stones, pearls). The barcode is Code 128 by default — universally readable by any cashier scanner — and the tag layout is configurable per tag type (item description, price, stone specs, store name, etc.).

What you need

• A Godex label printer. JewelTrak sends jewelry tags as raw EZPL commands, which is the language Godex printers speak; other thermal brands (Zebra, Datamax) and any inkjet or laser printer are not supported for tags.
• JSPrintManager (JSPM) desktop client running on the same computer as your browser. JSPM is the bridge between the browser (which can’t talk to printers directly) and your physical printer.
• One-time setup: install JSPM, plug in the label printer, and select it in JSPM’s settings.

JSPM runs on Windows, macOS, Linux, and Raspberry Pi — not Windows-only, despite the impression most label-printing software gives.

Tag printing needs a computer. There is no JSPM for iPad, iPhone, or Android, so the tag print buttons are hidden on touch devices rather than left to fail — on a tablet or phone you’ll see a short note in their place. Tags are sent as raw printer commands rather than as a document, and a picture of a barcode won’t scan reliably, so there’s deliberately no phone workaround. You can still browse and build a selection on Print Tags from a tablet; printing it needs a desktop. Parcel, diamond, colored-stone, and metal-lot labels work the same way, for the same reason.

Documents are the exception: invoices, memos, work orders, and appraisals can be emailed or downloaded as a PDF from any device, including a phone.

Printing a single tag

1. Open any inventory item’s detail page.
2. Click the Tag tab. The eight tag lines are filled in from the item; edit any of them.
3. Update Tag saves your edits to the item. Print Tag sends it to the printer.

Your tag style, font size, and printer come from My Settings — they’re per user, not per item, so you set them once.

Reading the tag preview

The preview beside the lines is drawn to the same measurements the printer uses, so you can fix a too-long line before wasting a tag:

• The dashed line is the fold. Every tag folds through the middle of its printable area, giving two faces. Depending on the style the faces are side by side or stacked, and the preview shows it the way your stock actually folds.
• Text is drawn at your real font size, in the printer’s own fixed-width character cell. Tag printers have no proportional font: every character takes the same space, so MMMM and iiii are the same width on the tag — and in the preview.
• Text that won’t print is shown faded, past the boundary it hits, with a note underneath. Two different things can happen, and the note says which:
  • “loses N characters off the edge of the tag” — those characters are gone. Shorten the line or abbreviate.
  • “runs N characters past the fold, onto the other face” — the ink lands on the tag, but on the wrong half, likely on top of the barcode. Still needs shortening.
• The footer states what it assumed — tag size, fold type, your font size in points, and your printer resolution — so if a preview looks wrong you can see which setting to correct.

A note on resolution: the printer’s built-in fonts are specified in points, which are a physical size, so a 6 pt line is the same height on a 203 and a 300 dpi printer and the same number of characters fit. A higher-resolution printer gives you crisper edges and better QR codes, not more room for text. If a line doesn’t fit, the only fixes are fewer characters or a bigger tag — Small (6 pt) is already the smallest font the printer has.

Printing many tags at once

For a freshly-priced batch of inventory or a re-tagging session:

1. Go to /print-tags (Inventory → Print Tags).
2. Filter or search to the items you want to tag.
3. Tick checkboxes for the items.
4. Pick the tag type and click Print Selected.
5. JSPM processes one tag per item in sequence.

Tag layouts

Each tag style has a fixed layout — where the lines, barcode, and stock number sit on the media — matched to that stock’s physical size and fold. You pick the style in My Settings (the preview there shows the tag image, overall size, and printable area); you control the content by editing the eight tag lines on any item’s Tag tab.

What goes on the lines by default comes from your tag views, which decide which item fields land on which line per inventory type (jewelry, stones, watches). Those are set up for you — ask support if a default line should carry a different field.

Tips

• If JSPM isn’t running, you’ll see a connection error in the browser. Start JSPM from your system tray and try again.
• To test a printer, print one real item’s tag — the preview tells you in advance whether anything will be cut off, so a test print is about the printer and the media, not the layout.
• The barcode encodes the StockID — scan it on the order entry screen to add the item to an invoice instantly.
• QR tags are available for shops that photograph through GemHub: set Barcode to QR code of the GemHub link in My Settings, and the tag prints a QR that opens the item’s GemHub gallery, with its text taken from the imported GemHub details instead of the tag lines. Because a QR tag is laid out for one label size at one resolution, the option only appears for tag styles that have a QR layout, and printing is refused if your Printer Resolution doesn’t match that layout rather than quietly producing a wrong-sized tag.

Label printer (parcel labels & metal-lot tags)

Separate from the Godex jewelry-tag printer above, JewelTrak prints roll/die-cut labels (Brother QL, Dymo LabelWriter, etc.) for things you don’t want on the jewelry-tag media — so you never swap the tag roll.

Set it up once per workstation in Settings → My Account → Preferences → Tag Printing:

• Label Printer — pick the roll label printer (used for parcel labels, metal-lot tags, etc.).
• Label Size — choose your media: Brother 1.1” continuous / die-cut, Dymo address sizes, or Custom (enter width × length; leave length blank for continuous).

These print via JSPM and auto-rotate to fit your media — no rotation setting needed.

Where you print them:

• Metal lot tag — on a metal lot (/metals/lot/…), click Print Lot Tag. Shows the metal, weight, lot #, source/seller, and any 30-day or police hold warning, with a scannable LOT-… barcode.
• Diamond parcel label — on a diamond’s detail page, click Print Parcel Label: shape · carat · color · clarity in the header; depth, table, girdle, Rap, and parcel # down the left; the 4Cs (cut, polish, symmetry, culet, fluorescence) down the right; and the lab/cert, measurements, big stock number, and barcode in the middle. Shape and the grades print as your short codes (OV, EX, N, F…), matching the legacy parcel label.
• Colored-stone parcel label — on a colored stone’s detail page, click Print Parcel Label: shape · carat · color · stone type in the header; geographic origin, treatment, and parcel # on the left; clarity and quantity on the right; lab/cert, measurements, stock number, and barcode in the middle.

The barcode encodes the lot or stock number, so you can scan a label to pull its record back up.
