Print styles

I really wanted to make sure that the print styles for Resilient Web Design were pretty good—or at least as good as they could be given the everlasting lack of support for many print properties in browsers.

Here’s the first thing I added:

@media print {
  @page {
    margin: 1in 0.5in 0.5in;
    orphans: 4;
    widows: 3;
  }
}

That sets the margins of printed pages in inches (I could’ve used centimetres but the numbers were nice and round in inches). The orphans: 4 declaration says that if there’s less than 4 lines on a page, shunt the text onto the next page. And widows: 3 declares that there shouldn’t be less than 3 lines left alone on a page (instead more lines will be carried over from the previous page).

I always get widows and orphans confused so I remind myself that orphans are left alone at the start; widows are left alone at the end.

I try to make sure that some elements don’t get their content split up over page breaks:

@media print {
  p, li, pre, figure, blockquote {
    page-break-inside: avoid;
  }
}

I don’t want headings appearing at the end of a page with no content after them:

@media print {
  h1,h2,h3,h4,h5 {
    page-break-after: avoid;
  }
}

But sections should always start with a fresh page:

@media print {
  section {
    page-break-before: always;
  }
}

There are a few other little tweaks to hide some content from printing, but that’s pretty much it. Using print preview in browsers showed some pretty decent formatting. In fact, I used the “Save as PDF” option to create the PDF versions of the book. The portrait version comes from Chrome’s preview. The landscape version comes from Firefox, which offers more options under “Layout”.

For some more print style suggestions, have a look at the article I totally forgot about print style sheets. There’s also tips and tricks for print style sheets on Smashing Magazine. That includes a clever little trick for generating QR codes that only appear when a document is printed. I’ve used that technique for some page types over on The Session.

— so you’ve made my point. that is why i program authoring tools that do make it “that easy” to make .epub, and .mobi, and .pdf.
