I'm building an application that has to use a POS printer to print a receipt on a button click. 我正在构建一个必须使用POS打印机才能在单击按钮时打印收据的应用程序。

I've never used a printer with JAVA before, so I have no idea, but I've done some research and I'm thinking of either formatting my receipt in a jtextarea and then printing it using the print() method, 我以前从未在JAVA上使用过打印机，所以我不知道，但是我做了一些研究，我在考虑将收据格式化为jtextarea ，然后使用print()方法进行print() ，

or painting it to Graphics2D first using paint(g2d) and then printing it with a printer job using the Printable interface. 或先使用paint(g2d)将其paint(g2d)到Graphics2D，然后使用Printable界面通过打印机作业进行Printable 。

Which would be easier? 哪个会更容易？ Thanks in advance. 提前致谢。

I've actually worked a lot with stuff like this. 我实际上已经在处理类似这样的事情。 I've tried printing with with Graphics2D which works fine but is very slow on a POS printer. 我曾尝试使用Graphics2D进行打印，该方法工作正常，但在POS打印机上速度很慢。 You usually want POS printers to be fast. 您通常希望POS打印机速度快。 POS printers have a serial communications interface for printing, which is how I'd recommend you to do it. POS打印机具有用于打印的串行通信接口，因此建议您这样做。 Have a look at: 看一下：

It's a library for interfacing with POS peripherals. 这是一个用于与POS外设接口的库。 The documentation isn't the best. 文档不是最好的。 You will need javapos libraries, javapos drivers for your specific printer, serial communication libs (RXTX) etc. 您将需要javapos库，用于特定打印机的javapos驱动程序，串行通信库（RXTX）等。
