CP1300 Printer Connection Problems?

[Tinker232]

Hey @reuterbal and @ALL,
I use the photbooth for weddings and birthday parties. I modified some things and it works very well, but the printer makes me crazy...
The CP1300 ist connected via airprint over a fixed IP-Adress 192.168.180.100. At first, the photobooth and printer works as expected, but after about 6 hours uptime, the printer looses the connection to the pi. The only thing you can do is restart the printer manually.
I try to provoke the behavior with a long existing printjob at the queue (no paper in tray) and filling the queue with more and more jobs. And after a while the printer lost the connection, but this occurs only when the uptime is over ~6 hours...
I noticed the "lpinfo -v" and "ippfind" commands shows the printer with his CP130053a843.local address. @reuterbal Please,

How can I replace the bonjour adress to my static IP-Adress?
Does anyone have an idea to fix the problem?

Thanks Tina :-)
