打印：不同打印机的打印效果？

[l_clove]

公司条件有限，只有一台喷墨打印机。请问有经验的朋友：程序在不同的打印机打印A4纸是否会出现不同的效果？

[bluebear88]

会，不同的打印机，分辨率不同，打印边距与不同，最终效果多少有点差异。

可能会不同，看你是用什么样的代码打印了，我写的一个套打程序在激光和针打下打印结果就不一样

不会，都是按你程序里面设置的打印格式打印。

贴一段代码，这段代码在喷墨和针打下效果不同
#define ITEMLENGTH 200
TPrinter * printer = Printer();

这段代码在喷墨和针打下效果不一样（喷墨正常）
