打印在 40mm x 15mm 尺寸标签上的条码 png 图像在打印且未被扫描时缩小为 20mm x10mm
Barcode png Image printed on a Label of 40mm x 15mm size is shrunk to 20mm x10mm when printed and not getting scanned
我在使用 code128 生成条形码并将其保存在 PNG 文件中时遇到了这个问题。
将相同的 PNG 文件提供给具有所需文档属性的打印机作业以在所需尺寸的标签上打印时，尺寸会缩小并且不会被扫描。
所提供打印件的实际尺寸 - 40 毫米 x 15 毫米。
标签上印刷的尺寸 - 20mm x 10mm
我正在将此属性添加到 PrintRequestAttributeSet -
pras.add(MediaSize.findMedia(40, 15, Size2DSyntax.MM));
但效果并不准确，我试着绕过那里的 x 和 y 参数值，打印的尺寸仍然在 25mm x 10mm 以内。
非常感谢任何打印所需尺寸条形码的输入。
我在下面给出了完整的代码细节。
(PS: 我正在使用 "Honeywell PC42t Plus" 热敏打印机打印，目前我的标签尺寸为 700mm x 280mm，我正在等待收到 40mm x 15mm 尺寸的实际标签。
所以这是为了测试，一旦收到实际标签，我就可以使用整个标签打印实际的 40mm x 15mm 条形码 space)

您可以使您的程序更短更快，并确保它始终打印 清晰 条码，方法是使用打印机语言而不是像使用条码打印机一样通用打印机。

谢谢@Erich。我已经使用了您给定的代码并更新了 ZPL 和 DP 语言的 printCommand。您更新的代码 (^LH) 能够打印条形码，但它没有被扫描（不确定，我尝试了一些变体但没有帮助），所以我在那里尝试了 DPL 命令，如此处的代码所示，它能够打印条形码并成功扫描。非常感谢您的帮助和指导。
