Hp laserjet 3055 offline when print out via networking when direct to the laptop, its working fine.......

Sounds like the netwok card is faulty or the network is not setup correctly in the printer.

If you can do the following and email me the output I should be able to help you.

Print the event log
The printer’s internal event log stores the last 20 errors and can be printed at any time. To print the
event log:
1 Press MENU until INFORMATION MENU appears.
2 Press ITEM until PRINT EVENT LOG appears.
3 Press SELECT to print the event log.

Also email a copy of the printer setup and test pages

Go to reports print configuration page it will give to netwrok configuration page check if the printer IP Address is in the same range of the IP Address of the laptopn.
If yes than check if you are able to open web browser of the printer on lkaptop using IP address of the printer if yes in laptop go to printer driver properties there go in Ports Tab and check if the Standard TCP/IP Port has IP Address of the printer of some other IP Addressif it is different IP Address than change it to the IP Addess of the printer.

Thanks and Regards.
