Where can I find better, more correct instructions to solve printing problems by editing prefs.js?

Instructions of "resolve printing problems | Firefox Help, line 6. Delete all the lines in prefs.js that begin with print_ and save the file. "do not match what is actually in my prefs.js file.

In other words, he didn't y not the lines * beginning * with "print" or "print_". However, the string of five characters 'print' is * very * many times buried deep in a line of characters, but never at the beginning of a line and rarely followed by underscore. So I have no idea what I'm actually planned to do to solve my problem.

It seems to me that this is just a badly phrased statement that might be more appropriate for someone who is familiar with the codification and development of software, which I'm not. I don't have the time, experience or knowledge to understand. I need more literal/explicit/specific instructions.

The printing problem I have is that I have to print via WiFi to a printer in another room wired to another computer, and Firefox seems to switch or possibly reverse scales fonts for information of margin and the text of the Web page. In other words, the title of the document, date, time, prints etc very wide and the content of the page text prints almost too small to read.

If there is a lot of user set prefs involved that need to be reset, then it's much easier to delete related lines of the prefs.js is each of them with the button straight on the topic: config page and click Reset.
This is the main reason (single) to edit the prefs.js file.
