网络打印机的处理方式通常与本地连接的打印机没有区别；它们首先在操作系统中设置，这使得它们可用于 Java 打印服务.

Network printers are typically treated no differently from locally connected printers; they are set up in the OS first and this makes them available to the Java Print Service.

如果您需要直接打印到 POS 打印机，它们通常有自己的二进制协议，您可以通过 TCP/UDP 使用该协议.例如，爱普生有 ESC/POS 系统.

If you need to print directly to a POS printer, they usually have their own binary protocol that you can use over TCP/UDP. Epson has the ESC/POS system, for example.

根据打印服务器的不同，您可以通过 CUPS/LRP/LPD/IPP 将 PostScript 直接发送到打印机.请参阅 http://www.cups4j.org 和 http://lpdspooler.sourceforge.net.

Depending on the print server, you may be able to send PostScript straight to the printer via CUPS/LRP/LPD/IPP. See http://www.cups4j.org and http://lpdspooler.sourceforge.net.
