Sony Ereader and fonts

I am new to this whole Ereader thing. I received one as a gift at Christmas. (Sony, PRS-T1.) I bought a novella from the Kobo store and everything worked just fine.

I recently purchased another book (EPUB format, no DRM) from the Kobo store and I cannot change the font size of the text on my ereader. When I try to change the font size, only the chapter headings change. (Note: did not have this problem with the novella.) As a result, it is unreadable on the reader as there are something like four lines of text per page and I have to switch pages every 5 seconds. I have the same problem using Adobe Digital Editions software, and sony software on my PC: the font size cannot be modified. The only software that works is the Kobo for PC software. This allows me to adjust the font.


Is there something wrong with this file? (as I have the problem in Adobe Digital Editions, not just on the Ereader). Or will it just not work with this software, or the Sony Ereader, and I'll have to buy it again from the publisher? Or would the epub I buy from the publisher be exactly the same as the one from Kobo? The reason I bought from Kobo is that I have a gift card to Chapters-Indigo (also works for Kobo).


The publisher (Carina) will not help me as I did not buy from them. I'd buy it a second time from the publisher, but I'm just worried I'll have exactly the same problem and I'll be stuck with two copies of a book that are essentially unreadable. Any ideas?

thanks,
Laura

thank you, Rob and Amadan.

It's not the reader, it's the file, as rob says. The publisher did a quick and dirty (i.e., cheap) job of converting the book to an epub, which means not formatting it properly with actual (resizable) fonts.

Click to expand...

But I can resize with Kobo software (even though I can't with Adobe or Sony) which is odd, isn't it?

Hmmmm...I'm not sure I have the patience or concentration or intelligence to edit epub files at the moment.

But, apparently my library system carries ecopies of this particular book, so I'm going to try that first.

Update: So I got a copy from the library and it works just fine!

Kobo insists there is nothing wrong with the file I downloaded from them (which DOES operate fine in Kobo software, just not in anything else, strangely) and that I should try redownloading it (which I have done multiple times already) or contact Sony. But I remain convinced something is up with that file....
