Here is my proposed text for the F2F slides WRT a potential "Mobile
IPP" effort.
1. Why Use IPP on Mobile Devices?
- Currently printing on mobile devices (smart phones, netbooks,
etc.) is hit-or-miss
- Usually no way to install printer drivers, and vendor-specific
solutions leave a lot to be desired (separate application, etc.)
- Printing is usually less "organized" - you print to the device
you are near (queue "love the one you're with" music :)
- Printing requirements are generally simpler (smaller documents,
etc.)
2. Mobile IPP Printing Use Cases
- EMail messages (and attachments)
- Web pages (boarding passes, directions, etc.)
- Photos (built-in camera)
- Notes, to-do lists, etc. created on the device
- All typically 1-3 pages in length
3. Mobile IPP Printing Experience
- Press "print" on phone
- Select nearby printer on Wifi network (DNS-SD/Bonjour/etc.)
- Select paper size and possibly options (duplex? quality?)
- Press "print" on phone again
4. How to Support IPP on Mobile Devices
- Mobile devices can already generate JPEG, PNG, XHTML, and PDF
data easily (even in bands of raster data) via existing, embeddable
(and often free) software libraries
- Mobile devices can already discover printers and send print jobs
via IPP easily via existing, embeddable (and free) software libraries
- Many printers already support DNS-SD/Bonjour, IPP, JPEG, PDF,
PNG, and XHTML-Print
- Missing piece: IPP standard to define interoperability
requirements
5. Outline of a Mobile IPP Specification
- Require IPP/2.0
- Define the baseline document-format's to support: JPEG, PDF,
PNG, and XHTML-Print
- Client (mobile device) must support generation of all formats
- Server (printer) must support at least one of the formats
(advertised via document-format-supported)
- Server must also support media and media-supported attributes
using PWG media names to select output size
- Server optionally supports other job template attributes
- Server scales to fit specified media
