我正在使用的Andr​​oid项目斑马RW420和我编码，我发现，即使在简单的测试使用ZSDK开发打印机演示打印机打印大量的多余的纸张时，它发出打印命令。在这种情况下，我测试了签名捕获和打印演示。我发现，如果我把它连接到电脑，并打印使用斑马Designer创建一个标签，它打印标签正确，没有多余的纸张（其实我不介意几毫米的额外在该情况下）。

如果任何人知道如何节省一些树木在这里，将是巨大的！

在code的问题是：

  connection.open（）;
ZebraPrinter打印机= ZebraPrinterFactory.getInstance（连接）;
GraphicsUtil G = printer.getGraphicsUtil（）;
位图图像= signatureArea.getBitmap（）;

g.printImage（图像，0，0，image.getWidth（），image.getHeight（），假）;

connection.close（）时;
 

解决方案

你有关键字 FORM 在你的CPCL标签吗？它通常在打印前

本通知打印机打印到顶级的形式设置打印机配置为之后形成饲料。要禁用它，您可以从您的格式中删除 FORM 关键字，如果你不需要它，或者你可以设置顶级的形式 0。

 ！ U1 getvarmedia.tof
 

会告诉你你的顶的形态，目前设置为

 ！ U1 SETVARmedia.tof0
 

将其设置为0，从而使 FORM 将饲料0点

I am using a zebra RW420 in an android project and I am coding and I find that even when simply testing the printer using the ZSDK Developer Demos the printer is printing lots of extra paper when it is issued a print command. In this case I am testing out the signature capture and print demo. I do find that if I connect it to the computer and print a label created using Zebra Designer it prints the label properly with no extra paper (in fact i wouldn't mind a couple of millimeters extra in that case).

If any one knows how to save some trees here that would be great!

The code in question is:

connection.open();
ZebraPrinter printer = ZebraPrinterFactory.getInstance(connection);
GraphicsUtil g = printer.getGraphicsUtil();
Bitmap image = signatureArea.getBitmap();

g.printImage(image, 0, 0, image.getWidth(), image.getHeight(), false);

connection.close();

Do you have the keyword "FORM" in your CPCL label? It's usually before PRINT

This tells the printer to form feed after printing to the top-of-form setting the printer is configured to. To disable it, you can remove the FORM keyword from your format if you don't need it, or you can set the top-of-form to 0.

! U1 getvar "media.tof"

will show you what your top-of-form is currently set to

! U1 setvar "media.tof" "0"

will set it to 0, so that the FORM will feed 0 dots
