If you want to display code or logs please surround it by three ` like this:

<?php echo $code_example; ?>
    @page { sheet-size: 58mm 200mm; }
            @page { sheet-size: 80mm 200mm; }
            p {
    font-size: 4vw;
}
body{
    width:58mm;
    height:200mm;
}

I have edited the custom css file and posted the above code but after print the items are unreadable. What am i missing here?
