Google Docs™ does not natively support a wide range of custom page sizes. This addon allows you to easily set predefined page sizes suitable for (Zebra) label printers.

It includes:
- Original imperial sizes (e.g., 4in x 1in, 4in x 6in), displayed in inches.
- A selection of common metric label sizes (e.g., 10cm x 4cm, 10cm x 10cm), displayed in cm.

The page orientation (portrait/landscape) can be toggled using the "▯ 🔁 ▭" menu item.
Margins are set to approximately 5 mm (14 points on all sides).

This addon only sets the page size and margins. For other settings like paper source or specific printer configurations,
you would typically use your printer's driver settings.
Use Google Docs™ File → Page setup for other document-level settings (e.g., orientation, paper size if it's a standard one).
Note: Using the native "Page setup" dialog might reset your custom page size if it's not a standard Google Docs size.
If that happens, simply re-apply the desired size using this addon (Extensions → Set Zebra Page Size → [Your Choice]).
