Already did it!
In my case, I was given the advice before I started making the comic, that it's way easier to make your pages in page format, and then to spread out the panels in a long scroll than to upload panels as a long-scroll and then try to arrange them into pages, so since I'd planned from the start to print a book, that's how I approached it.
The only changes in the print book of Errant are:
- It's in CMYK colour (so I had to tweak some of the bright colours to work, and it's generally a little duller... but people who haven't read the web version are still always like "waaaa-! So colourful!!!").
- It's at 300DPI and without the Tapas compression, so the art is sharper.
- One or two awkward early panels from the first pages where I wasn't settled into the art style were tweaked.
- The text and speech bubbles are smaller, because they don't need to be readable on a phone screen about half the size of a page, and need to be smaller because I don't have the extra gutter space.
- One or two lines of dialogue have been tweaked for grammar or feeling slightly out of character.
Mostly though, it's fairly close, so....

I funded the print run on Kickstarter, and now sell it on a dedicated website, just posting them out when we get orders.
