I have added a network printer, a Konica Minolta C253, via cups by its IP (http://10.0.0.42) under the http://localhost:631/ cups webfrontend on an Ubuntu 11.10 client.

I used the documented KOC353U.ppd in the process.

I was able to print exactly one page.

Afterwards, all I get in the printer's status is the message: "Network host '10.0.0.42' is busy; will retry in 30 seconds".

What is the problem here and how do I resolve it?
