If the printer is pausing between labels, there are two adjustments that can be made in the windows printer driver that will reduce the number of occurrences of the pause problem.
1. In the Ports tab of the driver, uncheck the "Enable bidirectional support" checkbox
2. In the Printer Memory tabs of the driver (there are two Printer Memory tabs, the first is located in Advanced tab > Printing Defaults... the second is located in General tab > Printing Preferences...) increase the Internal Memory Size times 2.
If the printer is still pausing, verify that you have followed step 1 and if you have then double the Internal Memory Size again. Keep doing this until the printer stops pausing. (10,240 is the maximum value for the Memory Size)
