Zebra LP2844 stops responding to ZPL commands or files

I sent a couple of zpl files to the printer to check it, and it worked fine.

After that, I received the basic zpl codes from the UPS and created the file and sent it to the printer using the Java applet, and now any zpl commands or files that I send to it do nothing.

I put it in a diagnostic dump mode, sent some commands, then clicked the feed, and it just printed out the list of commands that it sent .. so that they go through, at least, but don't print them.

It prints other data in order, for example, when sending an image to it.

You need to print the EPL code on the LP2844 printer. It does not respond to ZPL code.

My recent research shows that the LP-2844 and TLP-2844 are EPL only, while the LP-2844Z and TLP-2844Z support ZPL. Non-Z versions, originally called the Eltron LP-2844, also have very little RAM.
