The library no longer supports printing from any device except library-owned PCs and laptops. 

You can transfer your file to a library-owned computer with a USB drive. An even easier option is to save your file to any cloud-based site (for example, MS Office 365's OneDrive, Google Drive, Dropbox, etc.) and then open your file on a library-owned computer for printing.

If you're having trouble accessing your file from a library computer, please ask for help at the Circulation Desk.
