CSS Print Stylesheet:-

many of us working on css to style web page for the visitors
you may added this line before in your page

<link rel="stylesheet" type="text/css" href="cssfile.css" />

ok the css file now will affect the screen but what if we want the css affect the print
yes we want the visitor print the page but without the menu , advertisement .. etc
ok we will now create a  css file and we will name it print.css

now add this line to your page
<link rel="stylesheet" type="text/css" href="print.css" media="print" />
do you notice someting ??
yes , media=”print” this tells the browser to use this css file when print

concepts of print style sheet:-

1- adjust body margin
adjust the body margin so printed page margin will be as you want not the browser default
you can use this for example

body{margin:0;
border:1px solid #000000;
}
2- use one measure for your fonts and line height and related things:
you must use one measure for font size and related things like pt , em so it can display good on your printer

there is many situations that you need to set the default timezone before you use date or time function such as date()
for example if your script user not in the country that you have the server or hosting on and you want to record lastlogin time , yes you are in trouble
there is many ways to do that
