Have you try any other pictures? 发自我的 iPhone

在 2019年1月10日，上午7:16，David ***@***.***> 写道： I am able to print an image from android phone, but when I try from iOS, the printer prints the first few lines of the image, but then stops feeding the paper, and just keeps printing on the same line. I wonder if anyone else has come across this? I actually reproduced this behaviour in some other software that isn't part of this repo, so I am wondering whether it is a printer bug. Any help would be appreciated! I have attached pic of the result. Ignore the "hi there" that was from a previous test. — You are receiving this because you are subscribed to this thread.

I tried with the nyearprint app and it works

[januslo]

so what's the problem? nyearprint not meet your requirement ?

I need to create my own custom app. I am desperately trying to print images from iOS using your code but it doesn't work. It works on Android. On iOS the printer appears to get stuck when printing an image. Can you print images from iOS app?

[DavidStummer]

I tried to create the simplest image (a black square) and it still doesn't work. I have attached it.

FYI I fixed my issue by implementing a different esc/pos command for printing an image:

I already had this code for android (https://www.jianshu.com/p/c0b6d1a4823b) and it was a relatively simple matter of converting over to objective-c.

Hi @DavidStummer , I have exact issue like yours (except my printPic won't print any image and just got stuck there).

Could you elaborate more on how you managed to get past the issue? I'm interested in how you implement that different esc/pos command for iOS.

Thanks!

Hello
Did anyone found solution for this?
I am stuck when try to use printPic method on iOS. For others method it work well.
I am sure base64 format is correct.
The error code return when call printPic method: COMMAND_NOT_SENT, and I call 2 method in same time with printText and printPic but for printText it working.
