一、在内容模型里面新建一个printr.php文件，代码如下：
<?php
defined('IN_PHPCMS') or exit('No permission resources.');
//模型缓存路径
define('CACHE_MODEL_PATH',CACHE_PATH.'caches_model'.DIRECTORY_SEPARATOR.'caches_data'.DIRECTORY_SEPARATOR);
pc_base::load_app_func('util','content');
class printr {
private $db;
function __construct() {
$this->db = pc_base::load_model('content_model');
$this->_userid = param::get_cookie('_userid');
$this->_username = param::get_cookie('_username');
$this->_groupid = param::get_cookie('_groupid');
}
//内容页
public function show() {
$catid = intval($_GET['catid']);
$id = intval($_GET['id']);
$siteids = getcache('category_content','commons');
$siteid = $siteids[$catid];
$CATEGORYS = getcache('category_content_'.$siteid,'commons');
$this->category = $CAT = $CATEGORYS[$catid];
$this->category_setting = $CAT['setting'] = string2array($this->category['setting']);
$siteid = $GLOBALS['siteid'] = $CAT['siteid'];
$MODEL = getcache('model','commons');
$modelid = $CAT['modelid'];
$tablename = $this->db->table_name = $this->db->db_tablepre.$MODEL[$modelid]['tablename'];
$r = $this->db->get_one(array('id'=>$id));
if(!$r || $r['status'] != 99) showmessage(L('info_does_not_exists'),'blank');
$this->db->table_name = $tablename.'_data';
$r2 = $this->db->get_one(array('id'=>$id));
$rs = $r2 ? array_merge($r,$r2) : $r;
//再次重新赋值，以数据库为准
$catid = $CATEGORYS[$r['catid']]['catid'];
$modelid = $CATEGORYS[$catid]['modelid'];
require_once CACHE_MODEL_PATH.'content_output.class.php';
$content_output = new content_output($modelid,$catid,$CATEGORYS);
$data = $content_output->get($rs);
extract($data);
include template('content','print_r');
}
}
?>二、内容模型的模板文件按照模型指定的名字来建，如上面指定的是print_r.html文件，然后在这个文件就可以输出你想要的内容页的指定字段内容进行打印预览了，
模板代码如下：
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8" />
<title>打印_{$title}</title>
<meta name="description" content="使用打印机来打印{$title}">
<link rel="canonical" href="{go($catid,$id)}"/>
<style type="text/css">

</style>
<style type="text/css" media="screen">

rewrite ^/print/(.*)/([0-9]+).print /index.php?app=content&controller=printr&view=show&catid=$1&id=$2;四、需要打印功能的页面加上：
<a target="_blank" href="{APP_PATH}print/{$catid}/{$id}.print">打印本文</a>有两个小图，上传到images里
