Under latest client event I been noticing the below;

18-08-11 1:59:03 pm, Operation: Cancel Job, Selection Error: Unknown Object Identification (no such object) ,
User Name: 10.xx.xx.xx,
Address: 10.xx.xx.xx,
Object Name: TP-LG15

In fact this username and address is of Printer Server IP address. The printer TP-LG15 is working fine in a classroom and is on the network. But it just keeps coming on lately when I check latest client events as I get alerts on NDPS status.

Can someone please help as to why this is happening.

Shall I delete the printer and start again ?

I am running;
NetWare SP8-2b | iPrint 5.52 | Windows XP.
