PDF Trouble

Hello,
I'm a student at university and I'm trying to print off some lecture notes my lecturer has put up on our Intranet, unfortunately there is not a standard that all the lecturers put their lectures up in, eg some put them up in powerpoint some use pdf etc etc, one of my lecturers has put his up in pdf and its unable to be modified without a modifier and he has also made the background black...I want to print them all off to help with my revision except black background slides will drink my ink and seeing as he has 4 lectures each with ~50 slides for each I don't fancy that. I have downloaded a pdf modifier but this as far as i can tell would be an extremely slow method as I have to delete every background and then change the colours of each text, which I do not have the time to do is there a simple way to invert the slides so its white background black text? The pictures can be inverted I'm not that bothered by them. I cant upload any because they exceed the file limit.

Thanks!

You could see if IrfanView can open them. I just tried a quick one and it opened fine. There you can make it negative and print it.

 

can't your printer print inverted? i thought there's an option for that in adobe reader or in the printer settings somewhere. can't find it right now, though..

 

I downloaded irfanview but it wont open pdf's I downloaded and installed the plugin and also tried downloading ghostscript but im not sure that installed properly

I dont think so I had a little mess around but cant find anything like that :/

is there anything else I can try?

Cheers

 

try out some online pdf to word or pdf to powerpoint (do they exist, too, i've seen word ones). if you're lucky, they don't even copy the colors.

or try it with chrome, or google docs..

 

I gave up. I have wasted way too much time on these two lectures! I just printed them as they are and it raped my black ink! Oh well thanks for trying I think the lecturer had made a black box as the background instead of changing the background colour so when I tried editing it in all the various things I would set the bg as white and nothing would happen, plus I could move/delete it in some editing software. unfortunately doing that and then changing all the text colour to a darker one after would just be ridiculous.
Thanks anyways!

I swear it works...
