When printing labels through a Zebra ZP505 printer, you might face the scenario of the printer leaving blank fields in the labels.
This issue might relate to two usual scenarios:
Scenario #1 - The firmware and/or drivers of the printer are outdated and must be updated
Scenario #2 - You are trying to print labels which are not FedEx labels with the Zebra ZP505
The ZP505 is a FedEx-only thermal printer: https://www.zebra.com/us/en/support-downloads/printers/desktop/zp500.html
None of these are techShip issues, nevertheless, here are our recommendations for each case.
Scenario #1 - Update the firmware and/or drivers yourself, or having a software/hardware technician do it
Scenario #2 - Either use a different printer which supports printing the Carrier labels you are intending to do so, or update the drivers to ones provided in several internet sources to improve compatibility
