Hello @loouis-t, thank you for these updates. I've added some comments and suggestions to your PR. Feel free to comment back or reach out on Discord for any clarification! Usually, we tend to reduce screenshots within our documentation if the flow is straightforward, so that they do not replace the meaning behind words.

[emmi-odoo]

I think the flow is quite straightforward. Screenshots should be indicative and not leading (thus replacing the text). For this case, I would remove all screenshots.

[loouis-t]

It's not that obvious, the ePos homepage is pretty messy, i'd prefer to make things clear here

In case of hardware devices people are unfamiliar with the hardware interfaces.
The more screenshots we have the better.
Otherwise every day we get questions like "where can I find this button" and it's a giant waste of time for everyone

[Ysoroko]

I suggest we keep the screenshots and if needed you can make new ones / adapt these to follow guidelines and avoid thinks like red color.
But we need to show
every
single
step
(trust me I answer questions like these a lot)

The explanation can be perfectly clear textually as long as it includes enough detail about where to find the relevant tabs, menus, sections, and fields. Too many screenshots with heavy annotations tend to overwhelm the text — for example, step #3 is visually buried between two screenshots.

If visual support is truly needed, we could either include a GIF or you might consider creating a short video instead (either an internal one to share with those who have questions or a public YouTube tutorial).

The same applies to the screenshot of the ePos Printer setting below: once the location is clearly described, the screenshot doesn't add any value. We can keep the fourth screenshot (Device Management > Time Server > …), but the others should be removed.

@loouis-t Thanks for the improvements. Please see my comments and suggestions, especially regarding the screenshots.

@auva-odoo Can you double-check please?
