.netcore TSC打印机打印

此文章给出两种打印案例，

第一种是单列打印，第二种是双列打印

需要注意打印机名称的设置，程序中使用的打印机名称为999，电脑中安装打印机时名称也要为999。

以下是我在使用过程中总结的一些问题：

一 TSC打印机使用使用过程中遇到的问题

1、打印机刚连上就报警。

一般是纸张或色带安装有问题，纸张要放到档杆的下方。

2、打印机显示正常，DiagTool工具无法连接到打印机，无论点什么都提示“Port Open Error”。

如果使用USB模式，需要用线把打印机和电脑连接起来，同时打印机需插上网线。工具中，通讯接口选择USB，点击“读取状态”，正常显示待机中，点击“读取”，会重置工具中的各参数。

点击“网络设定”，指定IP地址，这里设置为192.168.50.222

如果用服务器连接打印机，这个时候已经添加了打印机，登录服务器，找到打印机，打开打印机属性-端口，打印机名称或ip地址设置为与打印机ip一致即可。

3、打印机打印完成后报警。

检查纸张，纸张安装过紧或档条没压住纸，都会导致此问题。

接下来上代码

二打印方式

2.1 单列打印

这种打印方式示例中，打印的位置是可以配置的
