This is an excellent effort. Was recently gone for 2 1/2 months away from the studio on a wilderness shoot - I could really have used this.
Thankfully the two printers left plugged in and running were HP Z Series printers and the micro-drip technology worked quite well but not perfect.
When I printed a diagnostic chart, first thing, the Magenta rectangle representing the magenta print head was missing. Ended up replacing that printhead but that was about all.
I think the program would have saved that expense and the printers would have been functioning perfectly once back home after that Long period away from them..
Thanks for posting this.
