Settings is short on purpose. The print rules are built in, so there are only a few choices to make: which image provider draws your pages, which paper you print on, how the screens look, and a daily safety cap.
Where to find it:
Click AiX Publisher, then the Settings tab. Your licence panel is at the top, then the Settings section, then Help & your account. Click Save Settings after any change; the page reloads with your new values.
Your licence:
The panel at the top shows your masked key, status, licensed email and the sites using your key. It is where you replace, refresh or deactivate your licence. See Installation And License Activation.
Default image provider:

The provider used first when making book pages and covers. The list shows all thirteen providers, with FREE next to the free ones. Pollinations.ai - FREE is the default because it works with no setup.
Books with a locked character always use Google or FLUX for their pages, whatever is picked here. Pick a provider whose key you have saved and tested on the Providers tab.
Paper type (spine width):
- White paper (default, best for coloring books): 0.002252 inch per page.
- Cream paper (common for story books and journals): 0.0025 inch per page.
This changes the spine width on your cover PDF. Pick the paper you will choose on KDP, and export again after changing it. See Spine Width, Paper Type And The Wraparound Cover.
Color scheme:

How the plugin's own screens look. It has no effect on your books. Click a swatch to preview it at once, then click Save Settings.
- Follow the ResultsAiX Hub, the default: uses the look picked in the ResultsAiX Hub, so all your ResultsAiX plugins change together, or WordPress Native if no Hub look is set.
- WordPress Native, Results Amber, Clean White, Ivory Cream, Snow Light, Developer Dark, Midnight Blue, Ocean Blue, Sunset Warm and Rose Pink.
Cost & safety:

The first line shows your text AI use over the last 30 days: the number of calls and an estimate of the cost on your own keys. Images are billed by your image provider, so they are counted, not priced.
The second line shows how many images were made today and your cap.
- Daily image safety cap (0 turns the cap off): the most images the background queue makes in one day, 500 by default. When it is reached, the queue pauses until the next day and the progress panel says so. Your own clicks, such as Reroll, always go through.
Help & your account:

Four cards: Your account portal (Open the portal), Need a hand? (Contact support), Troubleshooting (Open Diagnostics) and Training & docs (Open Training).
A real example:
Ella keeps Pollinations as her default provider, uses white paper for coloring books, and switches to cream paper just before she exports her journals. Her cap stays at 500.
Where are the print settings?
There are none to set. Trim size, bleed, margins and the gutter come from the book type and page count. The paper type is the one print choice left to you, because only you know which paper you will pick.
Tips:
- A lower cap, such as 100, is a good idea while you try a new paid provider.
- If the queue seems to have stopped, check Cost & safety first; a reached cap is shown there in bold.
