PrintSmash is a mobile application that allows users to print photos and PDF files stored on their Android devices using Wi-Fi communications. The app is designed to work with SHARP multi-functional copiers installed in convenience stores. PrintSmash supports JPEG, PNG, and PDF file formats, but encrypted or password-protected PDF files are not supported. Users can register up to 50 JPEG or PNG files and 20 PDF files, with each PDF file containing less than 200 pages. The transmittable file size is limited to less than 30MB for one file and less than 100MB in total when transmitting multiple files.

In addition to printing, PrintSmash also allows users to scan documents using their Android devices and save the scanned data on the SHARP multi-functional copier. The app supports JPEG and PDF file formats for scanned data, with users able to receive up to 20 JPEG files and one PDF file. However, users should be aware that scanned data may become large depending on the settings, and they should pay attention to the remaining space for storage. When uninstalling PrintSmash, all saved scanned data is deleted, but users can use the Share function to copy the data to other apps.

Overall, PrintSmash is a convenient app for users who need to print or scan documents while on the go. The app's support for multiple file formats and the ability to register and transmit multiple files make it a versatile tool for users. However, users should be aware of the limitations on file size and the potential for scanned data to take up significant storage space.
