Verification checklist — DYMO LabelManager

This is the family-specific checklist. Follow the verification guide for context — that doc explains why and what to do with the output.

Capture the terminal output and a photo of the printed label, then file your report on the Hardware verification issue template.

LabelManager prints on D1 tape. Confirm a 12 mm cassette is loaded (or whichever width your model supports) before running these steps.

Setup

npm install -g thermal-label-cli @thermal-label/labelmanager-node

Linux only:

• LabelManager devices are USB HID, so a generic udev rule for VID 0x0922 is required: SUBSYSTEMS=="usb", ATTR{idVendor}=="0922", MODE="0666".
• The LabelManager PC boots into mass-storage mode (PID 0x1001) before switching to HID (PID 0x1002). Use the shipped usb_modeswitch rule (or the CLI helper dymo setup linux) to apply the switch automatically.

1. Device is detected

thermal-label list

Expected: your LabelManager appears with the correct model name and PID, e.g. LabelManager PnP (0x1002) — usb.

2. Status is readable

thermal-label status

Expected: ready: true, no errors, the loaded tape width populated where the model exposes it.

3. Print a text label

thermal-label print text "verify $(date +%Y-%m-%d)"

Expected: a sharp tape label with the current date. The tape auto-feeds and cuts (or feeds for manual cut, depending on model).

4. Print an image

Expected: a graphics-quality print with no banding. Note: LabelManager has lower resolution than LabelWriter / Brother QL — fine details may not reproduce.

5. Tape-width matrix

If your model supports multiple tape widths (e.g. 6 / 9 / 12 / 19 mm), swap each cassette and repeat steps 2–3. Capture the printed labels side-by-side so the report shows which widths print correctly.

Model	Widths to test
LabelManager PnP / PC / Wireless PnP	6, 9, 12 mm
LabelManager 420P	6, 9, 12, 19 mm
LabelPoint 350	6, 9, 12 mm
MobileLabeler	6, 9, 12 mm

If you only have one tape width on hand, that's fine — just say so in the notes.

6. (LabelManager PC) Mass-storage mode switch

Confirm the mode-switch flow:

1. Plug the printer in fresh — Linux should mount a virtual CD-ROM for a moment.
2. The udev usb_modeswitch rule fires automatically.
3. The device re-enumerates as HID (PID 0x1002).
4. thermal-label list now shows the device.

Expected: total time ≤ 5 seconds; no manual intervention needed once the rule is installed.

7. (Browser) WebUSB live demo

Open https://thermal-label.github.io/demo/labelmanager in a Chromium-class browser, click Pair, select your printer, and print the demo label.

Expected: the same label content as step 3.

What to capture for the report

• The full terminal output of steps 1–4.
• A clear photo of at least one printed tape label (one per width if you tested the matrix).
• The exact @thermal-label/labelmanager-node version printed by thermal-label --version.
• Your OS and Node version.
• For LabelManager PC: confirmation the mode-switch ran without manual intervention.
