Need Help with Image

I have an image stored in a cuda unsigned char array, but I am not sure how to print it. Please help.

cudaChannelFormatDesc desc;
  desc = cudaCreateChannelDesc<unsigned char>();
 cutilSafeCall(cudaMallocArray(&array, &desc, imWidth, imHeight));
cutilSafeCall(cudaMemcpyToArray(array, 0, 0, pixels, imWidth * imHeight, cudaMemcpyHostToDevice));

memset(pixels, 0x0,  imWidth * imHeight);

printf("Reading image: bicol.pgm\n");
const char* image_filename = "bicol.pgm";
char* image_path = cutFindFilePath(image_filename, loc_exec);
if (image_path == 0) 
     printf( "Reading image failed.\n");
if (cutLoadPGMub(image_filename, &pixels, &imWidth, &imHeight) != CUTTrue) 
        printf("Failed to load image file: %s\n", image_filename);    

for(int i=0; i<imWidth * imHeight;i++)
 printf("%c", array[i]);
