用Java打印到标签打印机
我在打印标签打印机时遇到问题。下面的代码在一个标签上打印4个“标签”（附标签图片） 下面的代码打印到brother QL-500标签打印机上。它打印到3.5英寸乘1.1英寸的标签上 如果有人能帮助我更好地理解代码，那也太好了用Java打印到标签打印机,java,printing,label,Java,Printing,Label,我在打印标签打印机时遇到问题。下面的代码在一个标签上打印4个“标签”（附标签图片） 下面的代码打印到brother QL-500标签打印机上。它打印到3.5英寸乘1.1英寸的标签上 如果有人能帮助我更好地理解代码，那也太好了 import java.awt.Font; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.print.PageFormat; import java.awt.print.Paper

我有一个类似的代码，但不能使东芝便携式打印机在TPCL模式下打印，我的代码工作正常，但只有当打印机处于ESC/POS模式时。我的打印机是东芝B-EP4-DL 这是我的主要活动：

}我无法阻止它在标签上打印4张与图片所示相同的东西你“可能”运气好，我正好有一台DYMO LabelWriter 400，我会玩一玩，看看能发现什么Hello Friend的我在标签打印机（不是A4大小的纸）上打印条形码。小型打印机（标签打印机）存在打印对齐问题。所以在这里找到了很好的解决方案。这会提示我选择打印机吗？如何使它直接打印到打印机上？还有，我如何让它创建条形码？@RileyChilds 1-是；2-它可以直接打印到打印机上&如果你在谷歌上快速搜索Java条形码生成器，你会发现许多开源库应该可以满足你的需要。我希望它在打印时不使用Diologk，而使用diologless打印！如何将烧烤条形码添加到标签
