Novell (Orem, Ut)
The second IPP Interoperability Testing Event held March 9th to 12th. It was hosted by Novell in Orem Utah The Interoperability Testing Event was an unqualified success. There were 24 organizations participating. The participants were Apple, AUCO, Axis, Canon, EFI, Epson, Extended Systems, Fuji Xerox, Genoa, Hewlett Packard, i-data, IBM, JCI, Komatsu, Kyocera, Lexmark, Microsoft, Netsilicon, Novell, Ricoh, Shinesoft, Sun, Tektronix, and Xerox.
There were 11 IPP Client implementations and 27 IPP Printer implementations. Out of the 297 possible Client/Printer combinations 296 were successful in completing a simple "print-job" operation. That is a success rate of 99.66%. The previous Interoperability Testing Event had 8 Clients and 16 Printer with a success rate of 96.9%.
Other aspects of IPP were tested for the first time including HTTP chunking and security. We tested 127 combinations of chunking clients with IPP Printers. Of those tested 118 worked fine resulting in a success rate of 92.9%. We knew going into this test that some Printers did not yet support chunking. The limited security testing that was done was a complete success. There were 43 combinations supporting Basic authentication. They all worked. There were 2 combinations supporting Digest authentication and they worked. (There was one printer that knew going in its Digest authentication did not work. The printer participated only to prove it was broken.) There were three combinations that supported SSL and one combination that used Basic authentication over SSL. These also worked.
Approximately 20 issues were raised over the 4 day event. These issues will be brought to the IPP mailing list and discussed. The major benefit of the Interoperability Testing Event was bringing together the implementers of IPP from across the industry. The cooperation between the engineers was remarkable. All were sharing their IPP expertise and working together for the benefit of all. Every participating vendor will have an improved implementation of IPP as a direct result of this event.
The detailed results of the Interoperability Testing Event will be analyzed and a summary posted to the IPP site. This should be done by the end of this week. Detailed results and the raw data are available only to the participants. The raw data will be available in a day or so. I am following up on some test results that I do not see. I also have to convert a couple of hard copy tables to electronic format. I will send out email when the raw data and detailed results are available. If you want the data I have now just send me an email and I'll send it to you.
Thanks to all who participated,
