Troubleshooting

Bluetooth printing needs Chrome or Edge on Windows, macOS, Linux, ChromeOS or Android, with this file opened directly in the browser (not inside a preview pane). Safari, Firefox and iOS can't do Web Bluetooth — use Download PNG and print from the Print Master app instead.

Close the Print Master app on your phone first: the D30 only talks to one device at a time. Don't pair the printer in your OS Bluetooth settings; just pick it in the browser's chooser. If it isn't listed, tick "Show all devices".

Faint print: raise Darkness, or lower the threshold slider so thin strokes turn solid. Print lands off-centre on a die-cut label: print one blank-ish label first so the printer finds the gap.

This tool only formats and prints labels. It gives no dosing, handling or medical advice; follow the labelling and guidance that came with your product. Everything you type stays in your browser. Not affiliated with Phomemo.

Version history

v2.4 (14 Nov 2026) — phone-ready: single-column layout with the preview pinned at the top, installable to the home screen with offline support when hosted, and a short usage note.

v2.3 (14 Nov 2026) — horizontal centring: default margins changed from 1.5 / 3 mm to 2 / 2.5 mm (left / right), applied once on first open.

v2.2 (14 Nov 2026) — note / lot line prints larger and darker: slightly condensed to allow a bigger size, strokes thickened when the line is small, and the right column widened a little.

v2.1 (14 Nov 2026) — fix: v2.0 could open with an old saved layout and font (Standard vial + Monospace). Banner + Roboto Condensed are restored once, and settings are now saved as soon as the page opens.

v2.0 (14 Nov 2026) — header letters spaced out and thickened less; "RECON: / BUD: / LOT:" labels printed heavier; new "Shift down" setting (default 0.5 mm) to centre the content vertically.

v1.9 (14 Nov 2026) — Roboto Condensed is now the default font (switched automatically the first time this version opens) so the note / lot line prints larger.

v1.8 (14 Nov 2026) — Banner readability: taller header with larger, thickened white lettering so it doesn't fill in; right column widened and each line sized on its own (dates about 40% larger); labels fall back to bold on fonts with no medium weight.

v1.7 (14 Nov 2026) — sharper type: labels are drawn at 4× and averaged down before conversion to dots, and the Banner layout's "RECON: / BUD: / LOT:" labels use medium weight so their strokes print solid.

v1.6 (14 Nov 2026) — Banner layout re-proportioned to match the reference label: slimmer header bar flush with a thin frame, larger concentration column, right column sized to the reference.

v1.5 (14 Nov 2026) — seven built-in fonts (Roboto, Roboto Condensed, Inter, Open Sans, Source Sans 3, IBM Plex Sans, Atkinson Hyperlegible), embedded so they work offline; Roboto is the new default.

v1.4 (14 Nov 2026) — new default "Banner" layout: black header with name + strength, large concentration on the left, dates / note / lot on the right.

v1.3 (14 Nov 2026) — right margin setting (default 3 mm) so the strength and rule no longer run off the end of the label.

v1.2 (14 Nov 2026) — version number shown in the header, tab title and file name; this history.

v1.1 (14 Nov 2026) — left margin setting (default 1.5 mm); compound name suggestions; BUD +60 d; standard vial layout with name + strength header and auto concentration.

v1.0 (14 Nov 2026) — first build: label fields, QR, glyphs, borders, 1-bit preview, Bluetooth printing to the D30, PNG download, saved designs.
