I am new for css, still I'm trying to learn media types, i can't understand the usage of media type print, can anyone please explain what really does media type print
for an example what happen I use this css
#media print
{
p.test {font-weight:bold;}
}
It causes the CSS to only apply when the document is rendered to a printer … for putting on paper.
Suppose I have a webpage having black back color background then during printing It uses lot of ink. So, the thing I have to do is to change the background color to white and font color to black(if using white earlier).
This thing can be done by using
#media print
{
......
......//here write your code which you want during printing
}
this is an example for using #media print(But it have lot of other plus points also).
Yes, you can see the change during print preview

I am developing a web page that has light colored text on a dark background. When I try to print the page in black and white, the browser seems to automatically be inverting the colors so that it doesn't take a full cartridge to print. This is exactly what I was hoping for.
When I try to print in Firefox, the text is converted to a fully solid black. In Chrome, however, the text appears faint, and that is making it hard to read. Chrome still prints page numbers, time stamps, etc in the full solid black. How can I get Chrome to print the text on my page in that same full solid black?
Here's a sample showing the exact colors I'm using, and it reproduces the behavior I'm seeing on my actual page.
<body>
<form id="form1">
<div>
<table style="background-color:#2D3541; width:900px; height:900px">
<tr>
<td style="font-size:medium; text-align:center; color:#B7DBFF">Sample Text</td>
</tr>
</table>
</div>
</form>
</body>
What you can do is create what's known as a Print Stylesheet. This is a normal css stylesheet loaded in only when the user tries to print the web page in question. Normally browsers will aim to ignore certain CSS attributes which could lead to large amounts of ink being wasted (say the page has a background colour) and convert text to darker colours by assuming the background is white.
This can be overridden by creating a new print stylesheet <link rel="print" href="/css/print.css" or using media query #media print {...}
I find using a separate print stylesheet preferential as browsers won't load it until the user is intending to print the page.
by specifying the color of the the text that's causing issue in your print stylesheet or media query, you should be able to resolve issues where browsers aren't picking up your text style rules. If you're overriding a value set in another stylesheet, experiment with the use of !important if using a print stylesheet alone doesn't help things.
Ideally you should give your td a class to give you more granular control. Values in the style attribute take a higher priority than stylesheets, and Chrome may still be honouring the inline style attribute when the page is printed.
#media print {
.light {
color: #000 !important;
}
}
Smashing Magazine has some great resources on print styles:

This has been driving me mad all day. I at first went down the print settings route before realising that it's the "Print background colors and images" option in IE that's been tripping me up.
The last test case code I used:
<html>
<style type="text/css">body{font-family:Courier;}pre{display:inline;}</style>
<body>
<b><font color="#FFFF00">this is a test</font></b><br/>
</body>
</html>
When viewed in IE "this is a test" is displayed in bright yellow. However when printing or even print previewing it's rendered in what I'd describe as a muddy yellow. The same is true if I export to PDF via virtual PDF printer. If I enable "Print background colors and images" the correct yellow is used, but I understand from what I've read this option can't be set programmatically.
It's not just yellow, many similar colors end up the same as each other in the print preview, and I need to shade things according to error margin so can't just use ones that are very different.
So how to get round this??? I don't see why a setting for background colors is affecting foreground text like this (unless I can force foreground it? My HTML is only very basic and hasn't been used for a few years ...)
Cheers for any help
Try this css media query:
#media print {
body {
/*put your styles here*/
}
}
I'm not sure if IE supports it though. I'm not sure what versions your dealing with.
I changed the background color of a text, it works in side editor. But while printing background missing. How can I fix it.
Thanks in advance.
If using google chrome, it had an option can remove both backgrounds and images when printing that default value was enabled. Check out the print preview page and disable it.
Edit:
According to.. https://stackoverflow.com/a/11296931/1040870
Another try is using CSS to let webkit browser print:
-webkit-print-color-adjust: exact;
It works on my testing; And will overwrite the option I mention before.
Try the #media queries... #media print { propeties }

I have a HTML "report" page that contains amongst other things a HTML view that looks like this:
When you print preview this though, it looks a lot less nice :)
I know about CSS for printing, but what I don't understand is how my HTML is being interpreted like that - for example why do my blue borders come up fine, but my colored boxes (which are actually just empty divs inside a td cell) don't show up at all in the print preview. Also, why would the white text on black on the left not print like that?
Are there some rules for print-friendly css? Any suggestions here?
BTW - I tried previewing in both IE 10 and chrome - both pretty much did the same
I guess the problem is related to "background-color" and "background-image" properties that are ignored by default on many browsers (when printing).
For chrome you can add the following code to your print css, in firefox and IE you must select "print background" in the print dialog.
:root {
-webkit-print-color-adjust: exact;
}
EDIT: AN ALTERNATIVE APPROACH
Since you're looking for a way to provide readable information also on the printer you may provide specific content just for that:
in your HTML:
<td class="green_background blue_border">
<img src="img/green_bk.png" class="show_on_print">
</td>
<td class="orange_background blue_border with_star">
<img src="img/orange_with_star_bk.png" class="show_on_print">
<span class="hide_on_print">*</span>
</td>
in your stylesheet:
#media screen,print
{
.blue_border {border: 1px solid #00F;}
}
#media screen
{
.green_background {background-color: #0F0;}
/* hide something when displayed on screen */
.show_on_print {display: none;}
}
#media print
{
img.show_on_print {/* add size, etc. */}
.hide_on_print {display: none;}
}
you have to create also the images. The idea is to replace the background with some small sprites, or an alternative text only on printers. This works in any browser
The reason why you don't see the colored boxes is because the color is applied via background-color. This was one of the main sources of problems with printing HTML in the past, so many browsers ignore background colors and images to make the printout more readable (text is hard to read on a B&W printer when it's on top of a "gray" area).
In your case, this is problematic since there is no text.
Here is a question which explains how to turn background color printing on in Chrome. Other browsers have an option in the printing dialog.
Alternatively, "print" the page into a PDF file and then use a PDF viewer to print it. In this case, the browser might preserve the background settings.
Check if your browser suppresses background colours when printing.
I need to print report page that has couple of background images on it. But only these images are not printable. These images are logos actually for graph and hence very important in report.
I have another option that I can crop them and include in page as tag but this is last option. Hence before that I would like to know if there is any way to forcefully print these images? Can anybody help me out?
By default, a browser will ignore background css rules when printing a page, and you can't overcome this using css.
The user will need to change their browser settings.
Therefore, any image which you need to print should be rendered as an inline image rather than a css background. You can use css to display the inline image only for print though. Something like this.
HTML
<div class"graph-image graph-7">
<img src="graph-7.jpg" alt="Graph Description" />
</div>
CSS
.graph-7{background: url(../img/graphs/graph-7.jpg) no-repeat;}
.graph-image img{display: none;}
#media print{
.graph-image img{display:inline;}
}
Using this code, or similar code, means the image is used once in html and once in css.
The html version is hidden using css, and for print it displays as normal. This is a hack, but it will do what you want it to do. It will print the image.
Having said that, what you're doing is terribly bad practice. Nothing which conveys meaningful information to the user should be conveyed using css alone. Not only is it semantically incorrect, but it makes the graph less useful to users. An inline image is much better, and if you can, that's what you should use.
it is working in google chrome when you add !important attribute to background image make sure you add attribute first and try again, you can do it like tha
.class-name {
background: url('your-image.png') !important;
}
also you can use these useful printing roll and put it at the end of css file
#media print {
* {
-webkit-print-color-adjust: exact !important; /*Chrome, Safari */
color-adjust: exact !important; /*Firefox*/
}
}
