Next, I printed the same FedEx barcode mailing label through the hpcups driver with Okular. Then the printer produced the document but omitted the bar code. That is, the top half of the FedEx shipping label (that includes the barcode) is blank but the bottom part of the shipping label (that includes shipping instructions) prints out properly. That is, when you print though the hpcups driver with acroread then the print job gets stuck in the print queue and will not print. However, Okular will print the document omitting the barcode graphics part of the document. Again, nothing was contained in /var/log/syslog, however the attached cups_okuloar_log.txt has the contents of /var/log/cups/error_log. Personally, I didn't see anything peculiar in the cups error_log when printing with Okular although the document was printed incorrectly.
