NEW QUESTION 326
A customer is able to print most documents with their USB inkjet printer, but the system is unresponsive when printing a certain report from a custom application. Nothing will print until the computer is restarted and the printer is power cycled. A technician remotes into the PC and confirms that the spooler stops working when this report is sent. After clearing the spooler and reinstalling the drivers from the manufacturer’s website, the issue persists. No other sites using the application report similar issues. Which of the following is most likely causing the issue?
A. The manufacturer is curating content before it reaches the device to preserve ink.
B. The application has a bug that the developer needs to address.
C. The system is using the postscript language instead of the PCL.
D. Personal preferences have changed and documents with graphics are now online-only.
Answer: B
Explanation:
Since the printer and drivers function correctly with all other documents, and the spooler fails only when printing from one specific custom application, the issue likely lies within that application’s print-handling code. This indicates a software bug that must be resolved by the application developer.
NEW QUESTION 327
