Producing a PDF of a web page doesn’t preserve all graphics, layout and other design / functionality features, but it does enable you to save a record of some of the web page’s content, for reference. If you’d like to save a purely visual record of how the web page looks as it is, you can create a screen grab (simply for your reference, not necessarily for submissions).

Producing PDFs in Firefox
Go to Print (find this within the menu icon, which is made up of three horizontal lines, on the right hand side).
On the left hand side of the dialogue box which appears, click “Print” again.
From the “Name” drop down list, choose Foxit Reader PDF Printer, then click “OK”.
Navigate to where you’d like the document saved. You can also alter the filename here, if desired.
Click Save.

Producing PDFs in Google Chrome
Go to Print (find this within the menu icon, which is made up of three horizontal lines, on the right hand side).
On the left hand side, under “Destination”, click on “Change…”.
Click on “Save as PDF”.
Click the blue “Save” button.

Producing screen grabsOn a Mac, press Cmd + Shift + 4 together, drag the pointer over the web page, then let go; this saves a screen grab to your desktop. On a PC, press the “print screen” button to copy the whole of the screen’s content to the clipboard, then paste into an application such as Paint (where in turn, a Jpeg file can be saved). Alternatively, on PCs which have the Snipping Tool application: Open up Snipping Tool, drag the pointer over the web page, and then click the disk icon to save the file. Better still, Full Page Screen Capture is an extension for Google Chrome (available by using Chrome to visit this link, and pressing “Add to Chrome”) which allows you to produce a screen grab of the whole page of a website you’re viewing in Chrome (including the parts of the page you’d have to scroll to view). If you’ve added Full Page Screen Capture to Google Chrome, just press Alt + Shift + P whilst viewing a site in Chrome, after which the grab of the site will appear in a new tab. You can then right-click the grab, and choose “Save image as”. On a university PC, this sends the images to your Downloads area (in “Favourites” in File Explorer, or see: your username\ManW7\Downloads) whilst on a Mac, this gives you the option to rename the image and save it in a location of your choice.
