Super Mario Advance 4 E-Reader Help

So, I am trying to print out the E-reader cards for this game, from this site:

I've downloaded and unzipped the SMBA4 cards:

I've also downloaded the Nintendo eReader DotCode Printer from here:

So I've opened the printer application and put the cards in the "..." button, with the printer resolution at 600 x 600 and the quality at 600 DPI. However, when I try to print this, it's status turns to "spooling" and nothing prints. Could someone help me out? :confused:
