RT,想参考下,谢谢
后端接口返回文件流,怎么在uniapp里面导出
蓝牙打印机通用吗? 这边试的富士康lpk130 连接失败
图片打印逻辑不懂但是,佳博有现成的图片转码的接口https://www.poscom.cn/demo/zplimage.php,大佬受累看下~~
瀑布流好的实现方式百度了好久,利用css3实现的有flex,有Multi-columns还有Grid,但都有一个通病,就是数据都是从上往下,而不是从左往右。
意思是数据列的变化是1,2,1,2或者1,2,3,4,1,2,3,4等等这样交替,而不是先排列完第一列再来排列第二列,我滑到下面,如果数据有新的变化,新数据是在最后一列从上往下排列,这样我又得滑上去。很难受。
不知道有没有什么好的见解。
uniapp 中数字的大小不能改变设置了90 不起作
tsc.js原内容
data = "BITMAP " + x + "," + y + "," + width + "," + height + "," + mode + ","
jpPrinter.addCommand(data)
我修正后却打印出一团像条形码的黑块,图片格式是png,大小3kb
我修正的方式是直接从res把data拿过来用了,这一步是不是做错了
data = "BITMAP " + x + "," + y + "," + width + "," + height + "," + mode + "," + res.data
jpPrinter.addCommand(data)
小程序打印支持吗?我试了下不行

近期学习 uniapp
看过10几个例子, 一般都是 小程序和 app 图片缩放好使,
h5 的一般都没有效果, 偶尔碰到有效果的也是, 整个 h5 页面整体放大, 用微信扫描打开的 h5 页面,就没碰到过能图片缩放的, 包括官方的例子
希望大神, 如果知道能分享一下 , 谢谢了
试了半天都没效果,把codeArr置空,input的确空了,但是没法接着输入了,或者再输入直接就显示出上次的值
