2 hours ago @minusoneman Thank you for your report. We have also found this issue and here is a temporary workaround.
Star Micronics found that LAN printers cannot be found during searches and printing is not possible in any cases with the condition below.
| iOS 17 or earlier | iOS 18 | |
|---|---|---|
| Xcode 15 or earlier | Not occur. | Not occur. |
| Xcode 16 | Not occur. | Occur |
Root cause
Under investigation If this issue can be resolved on our side, we plan to release an updated version with the necessary fixes.
Temporary Workaround
Build with Xcode 15.
According to Apple's requirements, it is possible to provide deliverables built with the previous environment until March 2025.

Starting April 2025, apps uploaded to App Store Connect must be built with SDKs for iOS 18, iPadOS 18, tvOS 18, visionOS 2, or watchOS 11.
Description
We are experiencing issues with apps build with Xcode 16 (they work as expected when built with Xcode 15) running on iOS 18
Your device where the bug occurs

Your development environment
ProductName: macOS ProductVersion: 15.0 BuildVersion: 24A335
