Advanced printing settings

Most people only need the Wizard: it figures out the configuration on its own and you just enter the label size. But if you know your way around printers and want to fine-tune every detail by hand, there’s the Advanced settings screen.

How to get there

1. Open Printers

   In the Android app, go to Printers.

2. Tap Advanced

   On the saved printer, tap Advanced (or the Advanced settings link the wizard offers when the label doesn’t come out right).

What you can adjust

Each setting affects how the label prints. Change one at a time and check with the test:

• Label size — width and height (in mm) the printer uses for the test. The size of the labels you print day to day still comes from the template you pick when printing, not from here.
• Protocol — the “language” the printer understands: TSPL, CPCL, ESC/POS or ZPL. The wizard usually gets this right; only change it if you know which one your printer uses.
• DPI — the printer’s resolution: 203 or 300. It’s written on the printer’s spec sheet.
• Gap — the space between one label and the next on the roll. Use 0 for a continuous roll (no gap).
• Label with black mark — turn this on if your roll has a black stripe on the back that the printer uses to align (instead of the gap).
• Density — darker (faint lines, increase it) or lighter (smudged lines, decrease it).
• Speed — slower usually prints sharper.

Print test

The Print test button calibrates the sensor and prints a few check labels in sequence. Look at the result: the frame should come out the size of the label, sharp and aligned. If it doesn’t look right, adjust and print again.

When it looks good, tap Save. The settings work even without internet and sync on their own once the connection is back.
