You've not told us which version of Windows your laptop is running. I'll assume that it's new though (rather than secondhand or reconditioned), so it will be Windows 10 that you need instructions for.
If you want to see, say, Google when you start your laptop, you'll need to tell it to automatically open your chosen browser (Edge, Internet Explorer, Firefox, Chrome, etc). This link will take you to a video which explains how to do that:

If your chosen browser isn't already configured to use Google (or whatever) as its home page, you'll also need to tell it to use Google (or whatever else you like, such as The Answerbank) for that purpose. If you don't know how to do that please ask again, ensuring that you tell us which browser you use.
There should be a battery icon on the taskbar at the foot of your laptop's screen. Clicking on it will show you an estimate of how much time is left. (If the icon has gone missing, follow these instructions to get it back:

Computers don't connect directly to printers unless you use an Ethernet cable. With wi-fi they connect to a user's router which, in turn, connects to the printer. So the first thing you need to do is to install the driver for your printer onto your laptop. (If you're not sure how, please tell us the exact model of your Epsom printer and confirm which version of Windows you're using). Then, if you've not already done so, you need to ensure that both your laptop and your printer can connect wirelessly to your router.
