- Increased polling interval from 1s to 10s
- Use QtConcurrent::run to initiate a poll asynchronously to main event loop
- Do not initiate a poll if the previous poll has not completed
- Use copies instead of references to mCurrentAvailablePrinters in public API
- Allow printer selection directly from PrintView
- Print button bypasses the system print dialog, since label printing is quite different from typical printing tasks
- Separate button to optionally use system print dialog, if needed
