You must purchase the PDF export addon on the [Plugin Store] that appears in CLIP STUDIO with GOLD.
Unfortunately, non-Japanese version of CLIP STUDIO only has three selections: [PAINT], [ASSETS], and [ASK].

I NEVER knew this!! 
Yeah I don't think my assets page has a plugin section.
I'm going to see if I can find it though... thank you 
All is not lost but you will need an external software.
Download and install the open-source Scribus 1.5.3 Development Candidate from scribus.net.
- Run Scribus. [New Document] window will already be open.
- Set [Default Unit] to [Points]. Set your Width & Height. Set the [Number of Pages] for your comic. Click [OK].
- In order to add images you will need an [Image Frame] for each page. Best way to make an [Image Frame] for each Page all at once is to go up to the menu at the top and select [Insert] > [Frames...] Under [Type] select [Image Frame]. Under [Location] > [Page Placement] select [All Pages], in [Position of Frame] select [Top Left of Page]. Under [Size] select [Same as Page]. Under [Options] > [Source Image:] don't do anything here because you can't import multiple images(We will import multiple images a different way). Click [OK]. Now all your pages should have an X over it, that indicates that it has a blank [Image Frame], it should be same size as the Pages, if not, redo this part over.
- Be sure to zoom your view out so you can see many pages, you can do so from the bottom control.
- Now you must select one of the [Image Frame] from any of the pages by clicking on it, it doesn't matter which one, you just need one selected.
- Go to [File] > [Import] > [Get Image...] Or press [Ctrl+i]. Navigate to where your Comic page images are, select multiple images using [Shift] or [Ctrl]+Click, preferably in order. Double Click or Click [OK]. (You can't select multiple images in Scribus 1.4.6 from Stable Branch, that's why we needed Scribus 1.5.3)
- Click on the [Image Frames] you want your image to appear in order until you're done.
- When you want to export, go to [File] > [Export] > [Save as PDF...] > [Ignore Errors] > You can change where to output and name it, you can also change your resolution, then click [Save].
Done! That's the bare minimum. Now it's up to you to explore!
Notes:
- Menu > [Windows] > [Properties]. This window let's you conveniently reshape the selected [Image Frame].
- Menu > [Windows] > [Arrange Pages]. Let's you navigate your pages and even view them in double spread.
(You can drag these windows and snap them to the right or left side of the screen inside Scribus)
- If you go to Menu > [Page] > [Insert...] You can add more pages for your comic.
- You can press [ i ] then click or click drag anywhere to add an [Image Frame], then change it's size and location on the [Properties] window under the [X,Y,Z] section.
- Double Click on an [Image Frame] to add an image. You can change it's size and location and even have it scale to the [Image Frame] using the [Properties] window under the [Image] section.
- You can change the Default settings of many things within the Menu > [File] > [Preferences...] So you don't have to change them over and over.
- Alternative Image Import: If you're using Windows like I am(Windows 10). You can use the Windows system to browse to where your comic page images are saved and have that folder open, and you can drag an drop each one onto the Scribus [Image Frames].
No problem ThoughtfulBoxful. 
This tutorial is not just limited to CSP users either, so I hope it can help many people!
Are you 100% positive about that ? My print to pdf option says Microsoft Office pdf.... on my old pc I didn't have an Adobe sub and it let me print to pdf all the time. I'd test now but I caved and got a sub so not sure- hope that is a free option still

I was about to open a new thread to ask some question regarding CSP but since there is already an existing one I will just temporarily revive it to ask my question haha.
CSP rolled out a new update that includes auto save function, GREAT! But my biggest concern is if I was to install this new update, would it overwrite my old update and thus, make me lose all my shortcut, brush setting, downloaded asset on my current CSP? I don't see an option to safely update the program like any other program, but CSP seems to ask you to download an entirely new installer. I'm worried haha ;_;
Ah, no! It won't delete anything. At least I didn't seem to lose anything while updating, all my shortcuts + 3rd party brushes, assets etc were exactly the same after updating it today. It doesn't uninstall the previous version ( i think) just overwrites / adds some stuff.
But you need to open the program through Clip Studio to activate it for the first time after update to see the changes.
Thank you for the reply! That is reassuring : ) I can finally update and take advantage of this new auto save function in peace now //
So I feel like I just updated it. I downloaded, went through all the things to install, how do I know if CSP actually updated?
I went to Preferences and File but it doesn't have the same options like in the picture they showed on their website. Is it possible I just didn't install it correctly and CSP didn't update?
@beta1042 Did you make sure to select this?
And then CSP should have an option to update
Ok I click that and then what? It just doesn't have any clear options. My computer is saying the update is installed, but when I check the version of clip studio it is still saying the old version.
I have Clip Studio EX if that makes a difference.
Did you open CPS through Clip Studio?
You need to open the program through that for update to finish. I also had to delete my old icon I had docked and switch it to the new one that opened. I have EX version too, so that at least isn't the issue. You can check your version by Help -> Version information. This is what mine says about the version number.

When your update is successful, your interface will look slightly different from before too, making it easy to identify.
I hope you'll get it to work!
Yes. So I go to the Clip Studio, then I click Paint and it opens up the same CSP. Under help version info it still says version 1.6.2 If I try to download and install the new version again, my computer tells me I've already installed the latest version. There seems to be some other issue. I even had my husband who works for Windows do it too incase I was doing something wrong and he couldn't figure it out either.
I contacted CELSYS so hopefully they can help me out.
@beta1042 Mm ok I'll tell you what I did
I went to my 'delete programs' and uninstalled the OLD clip studio (light colored icon) because there is a clip studio for the old version and a clip studio for the update. Edit looking back i don't think i needed to do this
I went into my programs (C: thingy) and located the NEW clip studio, not the old one. Launched that
There were a couple of windows inside the new clip studio and one of them leads to the update i think? Or it was automatic
I hope that helps ;;
Ok this helped!!! Thanks so much
My husband said the reason it didn't work was because the original version I had was an English version, but the new update was a non-language specific version, apparently that made problems. I don't really understand but it works now, so yay!
