适用于批量无缝打印 ``` .pageT{ page-break-after: always; } ``` * 希望预览以上demo 将 第二位参数 `-print-to-default` 换为` -print-dialog`即可。以下为预览结果图  ## 注意事项 * 大量打印建议批量打印 并发调用可能会有异常的情况 * 条码后端生产 例如php 可通过输出svg格式条码到缓冲区并获取清空缓冲区 拿到svg字符串进行base64后放入img中拼接好前缀即可显示 * 对于更多高级的html css 打印用法可参考一下网址 * https://www.w3.org/TR/css-gcpm-3/ * https://developer.mozilla.org/zh-CN/docs/Web/CSS/@page * https://drafts.csswg.org/css-page-3/ * 对于绝大部分的html标签和css是支持的 但是也有很多不支持的或者需要新的方式替代 那么对最终显示样式不理想的 建议看一下调试日志 ### 调试与排查 * 需要在config.ini中设置`debug = False` 为 `debug = True` * 在安装目录中可查看`htmlPrint.log`文件中的日志 * 在调试完成后 一定要关闭调试模式 提高性能 * 如果出现预览正常 而打印不正常 不完整、乱码等情况 考虑是【乱码】驱动不对以及【不完整】打印可能是打印偏移量设置【水平偏移、垂直偏移】需要在驱动上进行设置 * 图像打印模糊不正常 需要【图形设置为无】 * 连续纸张或标签纸张都有不同设置 例如标签纸张有间距高 间距偏移等调整设置 具体联系厂家技术支持 * 如果遇到打印不清晰可能是字体问题 以上demo测试字体为`黑体SimHei` * 只要预览的没问题 大部分都是打印驱动设置问题 找厂家技术支持协调解决即可
