If your Epson ET 2550 not printing color, then follow the troubleshooting instructions given below to resolve it.
First, make sure that you are using the correct paper type setting to perform the print operation.
If the paper type setting does not match with the loaded media, then reconfigure the printer settings and check if the issue has been resolved.
Make sure to disable the Black/Grayscale or Grayscale option while performing the color print operation.
Check if the print head nozzles are clogged. If so, run a nozzle check to fix the Epson ET 2550 not printing color issue.
If running the nozzle check does not fix the issue, then clean the print head.
Make sure that the color ink cartridges are full. If the ink levels of the color cartridges are low or empty, then refill or replace them.
After refilling the ink cartridges, try to perform a color print operation on your Epson ET 2550 printer.
Make sure you are using genuine Epson paper and ink cartridges to perform the color print operation.
If you are performing the color print operation after a long gap, then run the Power Ink Flushing utility and try to perform the color print to avoid Epson ET 2550 not printing color issue.
