A laser printer uses patterns of static electricity to control where the toner sticks to the paper.  So the media cannot be conductive.  Copper will not work.

Is it possible to print on 0.035 mm copper foil with a laser printer?
Ok, so I've been using NSLog in objective-C for awhile now to debug and I know it's supposed to print to the terminal whatever I put in the parentheses. For some reason, it just stopped printing to the terminal and I'm not sure how to fix this error. I was wondering what other people would suggest doing to fix this problem. I've only included part of my code because I don't want to scare away someone from answering this simple (or at least I hope it's simple to fix) problem. When I run the code, the only two statements that print are "serverButton - Stage 1" and "serverButton - Stage 2 - Complete" but nothing else in between. FYI -(void)startServer is in another class called "Server" and I have made "server" a pointer to that said class.

-(IBAction)serverButton {
NSLog(@"serverButton - Stage 1");
[server startServer];
NSLog(@"serverButton - Stage 2 - Complete");
}

-(void)startServer {
    NSLog(@"serverButton - Stage 1");

    memset(&amp;hints, 0, sizeof hints);
    hints.ai_family = AF_UNSPEC; // set to AF_INET to force IPv4
    hints.ai_socktype = SOCK_DGRAM;
    hints.ai_flags = AI_PASSIVE; // use my IP

    if ((rv = getaddrinfo(NULL, MYPORT, &amp;hints, &amp;servinfo)) != 0) {
    	NSLog(@"ERROR: serverButton - Stage 1");
    	fprintf(stderr, "getaddrinfo: %s\n", gai_strerror(rv));
    	serverError = 1;
    	NSLog(@"Error");
    }
