Browser 是否从网站/web应用程序打印到标签打印机?
是否有任何已知的标签打印机可以接受来自网站或web应用程序的打印命令 特别是一次性标签打印机,如Dymo、Brother、Zebra等 是否有人成功打印到这些打印机上(不使用仅限Internet Explorer的黑客或ActiveX控件)Browser 是否从网站/web应用程序打印到标签打印机?,browser,printing,cross-browser,label,Browser,Printing,Cross Browser,Label,是否有任何已知的标签打印机可以接受来自网站或web应用程序的打印命令 特别是一次性标签打印机,如Dymo、Brother、Zebra等 是否有人成功打印到这些打印机上(不使用仅限Internet Explorer的黑客或ActiveX控件) 我认为,随着我们进入一个更加以浏览器为中心的世界,最终必须有一个解决方案。跨浏览器/平台兼容的网页/网页脚本不具备将打印机语言命令(如Zebra printer language[ZPL])传输到打印机所需的低级访问权限。为此,需要ActiveX控件/浏览器
我认为,随着我们进入一个更加以浏览器为中心的世界,最终必须有一个解决方案。跨浏览器/平台兼容的网页/网页脚本不具备将打印机语言命令(如Zebra printer language[ZPL])传输到打印机所需的低级访问权限。为此,需要ActiveX控件/浏览器插件/小程序/类似位的可执行代码。此限制不特定于打印机,来自浏览器,而不是打印机制造商
然而,许多标签打印机允许您像普通打印机一样对它们进行打印——只是那些打印到非常小的纸张上的打印机。您可以使用HTML/CSS布局标签。显示结果时,指示用户转到“文件>打印”,并在单击打印之前选择标签打印机 希望这有帮助,
Ben您可以从已签名的Java小程序或应用程序打印: 如果您格式化打印输出,使其适合标签,那么这应该是可行的
请注意,大多数现代浏览器都限制了对Java小程序的支持,因此您可能会在使用小程序时遇到问题,具体取决于使用的浏览器。特别是,谷歌浏览器将会。这些限制不适用于Java Web Start,它应该继续工作。Dymo打印机有一个浏览器插件,允许您从中打印。非常容易使用 几年后重新审视这个问题
联网的Zebra打印机易于打印。在一个项目中,我让Web应用程序打开打印机的插座,并在ZPL中为其提供指令 哇。我知道这是4年前提出的,但为了寻找一种从网络应用程序打印标签的强大方法,我花了整整一周的时间,我不得不在这里发言 以下是我的发现:
- DYMO似乎最有可能成为卓越的候选人。但事实证明,它只打印(a)自己的应用程序,或(b)使用SDK的东西。DYMO SDK使用的XML绘图模型过于复杂,并且在布局和样式方面受到限制。文档分散且难以理解(例如,常见标签尺寸的
值是多少?任何地方都没有标签参数的描述!)如此令人沮丧,如此令人失望 - 有一个,它可以为说EPL、ZPL、FGL、ESC/POS、EPCL和CPCL的设备启用浏览器打印。。。其中包括斑马系列。它需要大量集成(在标签打印机连接的设备上运行web服务器),但它可以工作
- 有一个设计良好的,适用于DYMO(除其他外),但需要从浏览器打印到PDF的中间步骤。他们还假设你永远不会将你想要打印的内容缩小到70%以下,这是不正确的
如果有人知道从浏览器打印的热敏标签打印机,而不是将你囚禁在陈旧的集成方法中,我非常想知道 您还可以尝试查找提供云打印解决方案的打印机,这意味着您可以通过互联网直接打印到任何打印机。Zebra现在有一个名为“BrowserPrint”的工具,它的工作原理与专为Zebra打印机设计的PrintNode类似。(与Printnode不同,它可以免费与Zebra打印机一起使用) 一些打印机还具有可用的ppd文件和/或可以在linux平台系统上的cups中配置,或者也可以通过linux进行连接和通话。(这意味着,通过构建一个简单的服务器守护进程,或者在linux机器上设置apache或lighttpd,甚至连接到打印机的raspberry pi,可以使用shell脚本、php、perl或其他方法打印到它)
这是我在C#中创建的,效果非常好。这是一个web应用程序。+1好主意。虽然以PDF格式发送标签可能更好,但这样比使用HTML更好地控制输出格式。“许多标签打印机允许您像普通打印机一样打印标签”。是否有任何打印机不允许我们像普通打印机一样打印!??我们有一个Dymo LabelWriter 450 Twin Turbo,可以通过浏览器打印。打印html时,我们在控制页边距方面遇到问题,但它确实会打印。@Timguiter-您能从浏览器中以静默方式打印吗?i、 e.在不出现打印对话框的情况下?@MarkCooper您可以使用chrome的kiosk打印模式进行打印。我已经成功地从页面打印到zebra打印机,而不需要用户做任何事情。@JayShepherd但我想这只适用于Chrome?-如此有限的用例:-(我在回顾你的步骤,我发现整个打印机世界的倒退非常令人惊讶。直接从浏览器进行打印似乎是一个明显的竞争优势,但通用解决方案仍然很少。我从Dymo for Mac下载了一个SDK,但我认为这是一个笑话,在经历了大量的VISE安装程序之后屏幕我最终得到了一堆applescript文件。到目前为止,最好的选择似乎是Zebra浏览器打印SDK。该选项很快将无法作为各种浏览器制造商使用
