<Edit: It seems putting epubs on the Kobo H20 isn't as hard as I thought. My problems may have been mainly from getting the epubs from project gutenberg. See below posts for their comments.>
Hi, I'm new here. I just got my Kobo Aura H2O, and figured out how to get it working right with normal epubs - mine were downloaded free from
www.gutenberg.org. This fixes issues of not being able to make margins smaller, and not being able to change line spacing.
*This does not tell you how to remove the page number at bottom of page. I like having it, so I never tried to remove it.
Here's what you do!
1. Download
Calibre on your computer.
2. Download your epubs from gutenberg, etc. on to your computer.
3. Open Calibre, and click top left button "add books". Select where the epubs were downloaded to and click "open" (on a Mac).
4. Hit Command-P on Mac, or Control-P on a PC (I assume), or click Prefences in the top bar, then click Preferences again.
Under Import / Export, click "Saving books to disk"
In the top left, uncheck two items - "Save cover separately" and "Save metadata in separate OPF file"
Under "Save template", you'll see this:
{author_sort}/{title}/{title} - {authors}
change it to this:
{title} - {authors}
Click Apply.
Close Preferences window.
5. Select your epub, and click the "Convert books" button near the top left of the screen.
6. Click "Look and Feel" and change "Minimum line height" to 0%
Click "Page Setup" and change "Output Profile" to Kindle Voyage. This has the same screen resolution as the Aura H2O. (You're changing the top list, leave the list on the bottom the same, on "Default Input Profile").
If you're using a different version of the Kobo, I'd assume you'd select "Kobo Reader" or whichever device has the same resolution as yours.
In the same screen towards the bottom you'll see: "Margins". Change Top and Bottom from 5pt to 0. This gives you more reading room by reducing excess extra space at the top and bottom of the display. Leave Left and Right Margins the same, at 5pt. That way the text won't be right against the sides of the display.
Click "OK"
7. Wait for conversion to finish (Wait for it to say "Jobs: 0" instead of "Jobs:1" at bottom right of screen),
Select the epub you converted. Right click and select "Save to disk", "Save only EPUB format to disk in a single directory" and select where you would like to save it to. (dropbox, to a sd card, to your documents)
OR
Click the little down arrow next to the "Save to disk" button near the top of the screen. Click "Save only EPUB format to disk in a single directory" and select where you would like to save it to.
8. Done! Now just upload/transfer epub to your Kobo! Use your usb cable, or Dropbox, or use Calibre as a server and download from there.
This allows for epubs to be formatted nicely, AND you can change the margins, line spacing, etc.
<NOTE: EPUBS sometimes display little grey page numbers on the sides of the screen and cover up a word or two of text if your margins are small. Go to settings, reading settings, and uncheck the box that says "Show Adobe EPUB page numbers". Big thanks to robko for letting me know.>
