I have an HP 3030 LaserJet connected via USB to my Linux desktop running Ubuntu 12.10. In the past, I have been able to print from my Macbook (OS10.6.8) over my wireless system, but somewhere along the line in upgrading Ubuntu, I have lost the connection.
The Macbook sees the printer, but will not print to it, generating the error message: "Network host 192:168.11.2 is busy; will retry in 30 sec." Alternatively, I sometimes get error message: "Cannot connect to printer; will retry...."
I have checked to verify that I have CUPS loaded, and even loaded Samba. But nothing works.
The http://Localhost:631 site shows the printer as "located" at URL: ipp://192.168.11.4:631/printers/hp-LaserJet-3030, and "connected" at ipp://192.168.11.2:631/printers/hp-LaserJet-3030.
