OK. I have a des-1250g switch (D-Link) when I hook a network printer up i have a problem. only when someone prints the network goes out. I than have to unplug the cat-5 and plug it into another port. than it works fine until I try to print agian. the document will print but right after that the network goes out? I have installed 2 network printers and had the same problem. I have no clue why it does this. could it be my switch? and one ever had this happen to them too?
