不使用UIPrintInteractionController进行打印 [英] Printing without UIPrintInteractionController

问题描述

我正在开发POS(销售点)应用程序.我能够使用UIPrintInteractionController popover成功打印.但是，当在屏幕上按下打印票按钮时，它应该直接打印而不会出现打印交互弹出框.我不确定这是否可能.

推荐答案

我与iOS Printing API进行了一些交互，并且我从未遇到过不使用UIPrintInteractionController进行打印的方法.作为iOS设备的用户，我不确定是否要想要进行打印而无需我说"so-so"，因为那样的话，任何旧的应用程序都可能会开始对打印机发送垃圾邮件.

I've interacted with the iOS Printing API a bit, and I've never come across a way to print without using the UIPrintInteractionController. As an iOS device user, I'm not sure I'd want a way to print without my say-so, because then any old app could just start spamming my printer.
