I would say that the primary considerations for unattended print runs should include:
1. Large ink capacity.
2. High capacity take-up system
3. Ability to easily and remotely monitor the printers activity from a smartphone or tablet (IOS or Andriod), and obtain near real-time information about the machine and it's status.
Based on those criteria, I would look at the HP Latex 360. HP announced a mobile phone app at SGIA in October, which will include very robust functionality for remote printer monitoring. Specific functions including:
- real-time ink level monitoring
- what jobs have printed
- What job is currently printing
- Notifications (ink low warnings, paper jam, media low etc)
- Status of other consumables in the printer (heads, maintenance cart etc.
- Remaining length on the roll (assuming that the media length tracking is enabled)
This Latex App is scheduled to ship in mid-January. Here is a page containing a video with more information on the mobile app:
