求一个图片打印的代码
要求有3：
1、能调出打印机设置窗口，选定打印机和纸张
2、图片能适合纸张页面
3、图片能按照1：1的打印，如果1：1超出了选定的纸张大小就自动分割到多个页面中打印

经常用Borland C++ Builder5编程，操作数据库时，报表打印是必不成少的。但BCB5自身所带的报表控件又显得贫窭矫捷性。所以，我想到了用TPrinter来打印报表。使用TPrinter必需要在轨范头部插手#include <vcl\Printers.hpp>
因为对于不是链页打印纸来说，断页很坚苦，所以，我所需要设定每页打印的记实数。下面就是我自己编制的一个每页打印30条合适前提记实的代码，写给巨匠，以供参考。
try{
//定位打印头
int x,y;
x=170;
y=150;

Printer()->Canvas->TextOut(x,y," -----服装请领记实-----");
Printer()->Canvas->Font->Size=10;
Printer()->Canvas->Font->Name="宋体";
x=190;
y=y+300;
//打印表格问题行
Printer()->Canvas->TextOut(x,y," ◇"+Trim(Label12->Caption));
y=y+80;
Printer()->Canvas->TextOut(x,y,"┏━━━━━━━━━┳━━━━━━━━━━┳━━┳━━━━━┳━━━━━━━━━━━┳━━━━━━━┓");
