Zebra LP2844 停止响应 ZPL 命令或文件
我向打印机发送了几个 zpl 文件来测试它，它工作得很好。
之后，我从 UPS 接收 Base64 编码的 zpl 数据，创建一个文件并通过 Java 小程序将其发送到打印机，现在我发送给它的任何 zpl 命令或文件都不起作用。
我将其置于诊断转储模式，发送了一些命令，然后点击提要，它只是打印了所发送命令的列表..所以它们至少正在经历，但它不会打印它们。
它可以很好地打印其他数据，例如向其发送图像时。
I sent a couple zpl files to the printer to test it and it worked fine.
After that I was receiving base64 encoded zpl data from UPS and creating a file and sending it to the printer via a Java applet, and now any zpl commands or files I send to it are doing nothing.
I put it in diagnostic dump mode, sent some commands, then hit feed and it just printed a list of the commands it was sent.. so they're going through at least, but it won't print them.
It prints other data fine, for instance when sending an image to it.

您必须将 EPL 代码打印到 LP2844 打印机。它不响应 ZPL 代码。
You have to print EPL code to a LP2844 printer. It does not respond to ZPL code.
我最近的研究似乎表明 LP-2844 和 TLP-2844 仅支持 EPL，LP-2844Z 和 TLP-2844Z 支持 ZPL。非 Z 版本最初称为 Eltron LP-2844，RAM 也很少。
My recent research seems to indicate the the LP-2844 and TLP-2844 are EPL only and the LP-2844Z and TLP-2844Z support ZPL. The non-Z versions, which were originally called the Eltron LP-2844, also have very little RAM.
我想补充一下其他答案，即在我一直在调试的 Linux 系统上，LP2844 模型似乎只响应 EPL2 代码，而不响应 EPL1。其他答案似乎没有区分这两种类型的 EPL，但在模型和语言匹配方面似乎是正确的。
I would like to add to the other answers that the LP2844 model specifically only seems to respond to EPL2 code, not EPL1, on a Linux system that I've been debugging. Other answers don't seem to distinguish between these two types of EPLs, but otherwise seem to be correct in the model and language matches.
andyknas 和 Bluby 的答案是正确的，添加了 Zebra 官方文档来源明确将 LP 2844 称为仅 EPL，将 LP 2844-Z 称为 ZPL 仅有的。

andyknas and Bluby's answers are correct, adding an official Zebra documentation source that explicitly calls out the LP 2844 as EPL only and LP 2844-Z as ZPL only.
