I think we may have rulled out the driver with the suggested test but I'll let you be the judge based on the information below:
I was able to download and install the Gutenprint and add the driver and print from the printer using that driver for non .PDF files successfully.

Next I attempted to print the .PDF file for the Click-N-Ship from the post office and it errored out.
I've included the error log from the Gutenprint attempt to print the .PDF below as well as a snapshot of the error.
The Job Message is the same: /usr/libexec/cups/filter/pstocupraster failed.
Please let me know what might be next or if you need any further information from the way I have it setup currently.
And again, thanks for your assistance helping me troupleshoot this.
Cheers,
Justin
