Comment 65 for bug 973270

I have read a few dozens of bug reports regarding this and similar issues always with the same message:

"Unable to add document to print job"

All bug reports are misleading the real bug fixes.

I can confirm that #43 is not an accurate explanation for what is happening and is a lame explanation. (sorry, had to)

server: running an ubuntu 12.04 (upgraded from 10.04) server with cups 1.5.3-0ubuntu1.

client1: running an ubuntu 12.04 (fresh install) client with cups 1.5.3-0ubuntu1.
client2: running an ubuntu 12.04 (upgraded since 8.04) client with cups 1.5.3-0ubuntu1.
client3: running an ubuntu 12.04 (upgraded since 9.04) client with cups 1.5.3-0ubuntu1.

all clients share the same cupsd.conf and printers.conf. all clients on the same network.

server is connected to printer through jetdirect. test page from cups is ok.

all clients connects to cups server using http://server:631/printers/printer

server requires no authentication for printing, all the internal network can use this cups server.

client1: (FAILS)

#61 is not a solution for the problem.

I can also confirm that this bug happens exactly the same way in a macbook air with cups 1.5.something with exactly the same server. (Sorry I have no logfile).

Therefore, I conclude from my readings:

"Printers don't respect ipp."

"Then I'm not using ipp for printer comm."

"Cups servers can't communicate with each other using the same ipp version."

"Cups doesn't respect it's own ipp."

My opinion: This is a cups bug.

worth checking: (with despise)

Sorry for the ranting style comment. Sometimes it's the only way. Hope it helps.
