I also see all of the line numbers on screen. But not on the paper printout. I am using the latest version of Firefox. When I tried to print out the listing using Chrome, I couldn't get it to work at all. Same with Internet Explorer.

If the only issue is when printing then you can always copy and paste into a different editor and print from there. A bit of a pain but then how often do you need to print out code.

Andy,

I already tried that. You should too before suggesting it. When you copy and paste you get the line numbers on one set of pages, followed by the actual lines of text on a second set of pages.

I just printed out my source via mbed to a pdf file. And in that file all line numbers including ones with bigger than 100 are present without problem. So I suppose the problem is in your "printer driver." Can you try with other printer driver or try layout setting in that driver?

Motoo, Thanks. I didn't try exporting via pdf yet. That might be a work-around I can make use of. Instead, I have been looking at the .html that is being generated. It has some issues, one of which is setting the line-number table cell width to 26px, which is not enough for 3 or more digits.

Bill,

I did try it, it works fine. You misunderstood what I was suggesting.

I didn't mean copy and past the line numbers and code together, that's a stupid idea. Copy and paste just the code into an external text editor that can add line numbers to the file. Just about any code editor can do that for you. My personal preference is visual studio, I like the flexibility to get the auto formatting just how I like it and much as I hate to give Microsoft credit it is a far better IDE than something like Keil.
