Final answer:
The correct option is 2) update the printer driver software. The most likely solutions to resolve the color discrepancy issue in printed photos are adjusting the color settings on the printer, updating the printer driver software, or using a different brand of ink cartridges.
Step-by-step explanation:
One option that is likely to resolve the issue is to adjust the color settings on the printer. This can help align the printer's color output with the original colors of the photos. To do this, the customer needs to access the printer's settings menu and look for color adjustment options. Another option is to update the printer driver software. Printer driver software helps the computer communicate with the printer properly, and updating it can fix any compatibility issues that might be causing color discrepancies.
Using a different brand of ink cartridges is also a potential solution. Different ink cartridges can have different color profiles, so trying a different brand may result in more accurate color reproduction. Contacting Photoshop for assistance is not likely to directly resolve the issue, as it is related to the printer and its settings. However, Photoshop may be able to guide you on how to optimize color output for printing.
