Two possibilities are the port configuration and the type of serial cable.
The printer has a feature that will try to match itself to the PC's configuration. Press and hold the feed button until the green status led flashes three times. While the led flashes send a ZPL format to the printer (hopefully you can do this through Design Pro by trying to adjust the printer or print labels, but the labels will not print). When the printer and PC are synchonized, the led changes to solid green.
If you can synchonize but still can't print, the problem might be the serial cable; not all serial cables will work. You should use a full null model cable (all pins connected except 1 and 8).

By gaps, do you mean a "void" area ? Over time, the elements on the printhead will wear down and finally they won't transfer heat to the ribbon. This causes a gap or void area. Usually the elements go out one or two at a time. If the area that is worn out is supposed to be printing bars for the barcode, this will cause the scanning problem you are experiencing.
The best way to see if elements are worn out is to design a label that has a thick solid black line across the label or a solid black box. You will see white vertical lines in the areas where elements are worn out. Another method would be to use the widest and longest label you have and print a 'pause" test label. This is done by turning off the printer, pressing and holding on the PAUSE key while turning on the printer. Hold the pause key for 10-15 seconds and when the printer is done with it's power on self test, it will start printing out a test pattern label which includes a nice black area where you can look for the white vertical lines.
Hope that helps !

The gaps run in the direction of the label feed? You have a bad printhead. Bad dots on the printhead prevent it from printing your format in the areas that you see the blank lines.
There is no easy fix other than replacing the printhead. You can prevent (or actually prolong the time between failures) in the future by periodically cleaning your printhead. It's recommended that you clean the printhead after every roll of labels. The printhead is underneath the hinged assembly. Over time, ribbon or adhesive from the labels builds up and causes dots to go bad - creating the blank lines you see. Clean your new printhead with rubbing alcohol.

the problem can be on the software that bild the label format, not on the printer.

Are the serial numbers all the same length?
