This email sent to site_archiver@lists.apple.com I received a complain from customer about an error occurs and is coming from NSStream. Basically the Cocoa code is written using NSStream. It is rather simple, the Mac connects to the printer and send raw printer data direct to printer either by Bonjour or a fixed IP. Somehow for this customer encounter the problem during sending data to printer an error occurs. The mac needs to reboot to resend again. There are many other customers' sites that are using the same software I developed but does not encounter the same problem. Below NSStreamEventErrorOccurred event returns a NSError with the following in Japanese. I can't read Japanese, so here is the google translate in English, TCP/IP Error 65 : 操作を完了できませんでした 。 ホストへのルートがありません I tried looking up for the NSError code 65 but can't find it in the listing.
