Linda,
We do have a "work around" but it is again just that. We have plans to more tightly integrate USB support for the thermal printers but for now you will have to follow the instructions listed in the support tab. Click support in the upper right corner, then select find answers, then type in "USB" in the search text. Answer ID 117 will give you the details of how to configure your computer to allow for USB access to the thermal printers.
Thanks,
Matthew McMaster
