Mac OS X上的Java App无法正确打印字体

2023年3月28日 275次阅读

我最近发现我写的徽章打印程序在
Windows上运行良好多年没有在MAC OS X上正确打印.我使用的是Arial truetype字体.该程序似乎显示基本字体,没有适当的缩放.我正在使用intellij和jdk1.7.0_15.字体在屏幕上正确显示,但在打印到打印机或pdf时则不会.当我使用GraphicsEnvironment.getAvailableFontFamilyNames列出控制台上程序可用的字体时,Arial被列为其中之一.当我直接从字体文件加载字体时,它可以正常工作.我一直在追逐我的尾巴超过一天,任何建议将不胜感激.这是演示我的问题的代码……

最佳答案 我写了一篇关于这篇文章的博文,名为
Printing is Broken on Mac OS X with Java 7,其中包括我发现的所有内容,包括原因,错误报告,以及我们现在的解决方法.简短的版本是它看起来像苹果的Mac OS或Java 7中的一个错误,并且在撰写本文时它仍然没有修复.
