Hi ALL, I recently withed from CentOS 3 X server to CentOS 4.5. It works fine other than printers. there are many printers connected to it. We have configured the commnad printconf queue type is Networked UNIX (LPD) Some times, we will be able to print , But, some times, We will NOT be able to print. We can ping its ip address. Even, when we can't print, We can ping its ip address. When we check logs , we see something like this. [Job 888] Unable to connect to printer; will retry in 30 seconds...: Connection timed out Then, What we do is , We go to application, system setting, printing and when we get the window, We click apply button, Then, again, We will be able to print. Could u pls let me know why? But, When We used CentOS 3X, it worked fine. No problem at all. here are rpms installed on CentOS 3X [root at lwlsvr_old root]# rpm -qa |grep cups cups-1.1.17-13.3.32 cups-libs-1.1.17-13.3.32 [root at lwlsvr_old root]# rpm -qa |grep samba redhat-config-samba-1.0.16-5 samba-common-3.0.9-1.3E.5 samba-3.0.9-1.3E.5 samba-swat-3.0.9-1.3E.5 samba-client-3.0.9-1.3E.5 But, on CentOS 4.5 , We get issues. here are rpms installed on CentOS 4.5 [root at lwlsvr ~]# rpm -qa |grep cups hal-cups-utils-0.5.2-8 libgnomecups-0.1.12-5 cups-1.1.22-0.rc1.9.20 cups-libs-1.1.22-0.rc1.9.20 [root at lwlsvr ~]# rpm -qa |grep samba system-config-samba-1.2.21-1.el4.1 samba-common-3.0.10-1.4E.11 samba-3.0.10-1.4E.11 samba-client-3.0.10-1.4E.11 Hope to hear form you. -- Thank you Indunil Jayasooriya
