Hi! I am writing Cups filter driver for printer Tysso PRP-085IIIT. This printer worked perfectly when connected by usb or serial cable, but when connected by ethernet cable it printed very slowly. For example, printing of one page takes 30 minutes! :) To exclude my code from this problem i run REDIR program on the Windows computer and set Cups printer address to this printer and the print test has successfully ended. I ran WireShark and send some data to printer again and I received many TCP DUP ACK packets in response. And more, when i made dump by WireShark of the tcp stream in case of printing with Windows, in these packets there were no TCP DUP ACK packets. I tried different kernel versions and net.ipv4.tcp_congestion_control algoritm, but had no results :( I am stuck :( How can I override this network problem? P.S. printer address is 172.16.11.99 http://www.kaa.org.ua/prp085iiit_linux.dump http://www.kaa.org.ua/prp085iiit_win.dump -- To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
