Introduction

When it comes to printing code snippets, especially from programming languages like Python, it's essential to have a clean and readable output. However, achieving this can be a challenge, especially when dealing with CSS styles that may interfere with the printing process. In this article, we'll explore some CSS improvements that can help you get the best results when printing code snippets.

The Problem with Printing Code Snippets

Printing code snippets can be a bit tricky, especially when it comes to programming languages like Python. The issue lies in the way CSS styles are applied to the code blocks, which can result in unwanted indentations, stripped-out colors, and other formatting issues. To overcome these challenges, we need to make some adjustments to our CSS styles.

Adjusting the lang-python CSS

One of the primary issues we encountered was the extra indent added to the first line of Python code in each code block. To resolve this, we made some adjustments to the lang-python CSS. Here's the updated code:

.lang-python {
  padding: 0;
}

By setting the padding to 0, we ensured that the code blocks would not have any extra indentations, making it easier to read and print.

Preserving Colors in Print Output

Another issue we faced was the stripping out of colors from the print output. This was particularly problematic when it came to code block backgrounds, which would lose their colors when printed. To resolve this, we added the following CSS code:

@media print {
  body{
    -webkit-print-color-adjust: exact; /*chrome & webkit browsers*/
    print-color-adjust: exact; /*firefox & IE */
  }
}

This code tells the browser to preserve the colors in the print output, ensuring that the code block backgrounds and other colors remain intact.

Adding Page Breaks

Finally, we added some code to insert page breaks between code blocks. This is particularly useful when printing long code snippets that span multiple pages. Here's the updated code:

.pagebreak { page-break-before: always; } /* page-break-after works, as well */

By adding this code, we ensured that each code block would start on a new page, making it easier to read and print.

Conclusion

In conclusion, making some simple adjustments to our CSS styles can go a long way in improving the printing of code snippets. By setting the padding to 0, preserving colors in the print output, and adding page breaks, we can ensure that our code snippets are printed in a clean and readable format. Whether you're a developer, a teacher, or simply someone who likes to print code snippets, these CSS improvements are sure to come in handy.

Additional Tips and Tricks

Here are some additional tips and tricks to help you improve the printing of code snippets:

Use a consistent coding style: Make sure to use a consistent coding style throughout your code snippets to ensure that they are easy to read and understand.
Use comments: Use comments to explain what each code block is doing, making it easier for others to understand the code.
Use a code highlighting plugin: Consider using a code highlighting plugin to highlight the code and make it easier to read.
Test your code: Test your code thoroughly to ensure that it prints correctly and that there are no formatting issues.
