推荐答案

该代码用于将原始打印机数据发送到打印机，有效地绕过打印机驱动程序，通常将其转换为打印机硬件可以理解的内容。它希望从文件中读取的数据已经与您正在使用的打印机的确切品牌和型号兼容。



PDF文件不是，它是一种通用的文件描述语言，需要翻译并通过打印机驱动程序发送。



你现在正在做的是将日语到斯瓦希里语字典有效地传递给瑞典语，并期待他理解故事......：笑：



如果要打印收据（带图像与否），请使用 PrintDocument [ ^ ] - 链接包含一个示例。

That code is for sending raw printer data to a printer, effectively bypassing the printer driver which normally translates it into something the printer hardware can understand. It expects that the data it reads from a file is already compatible with the exact make and model of printer you are using.

A PDF file is not, it's a general purpose file description language, which needs to be translated and sent via the printer driver.

What you are doing at the moment is effectively passing a Japanese-to-Swahili dictionary to a Swedish speaker and expecting him to understand the story... :laugh:

If you want to print a receipt (with an image or not) look at using a PrintDocument[^] instead - the link includes an example.
