220-1101 Hardware and Network Troubleshooting Practice Question
A user reports that their desktop computer, connected to a network printer via Ethernet, outputs garbled text when printing. The same user can print correctly using a USB connection to the same printer. Other users on the same network can print to the printer normally. The technician has already reinstalled the printer driver on the user's computer. Which of the following should the technician check NEXT?
⚠ Common exam trap
Many exam-takers assume garbled text always indicates a driver or physical connection problem, overlooking the print processor and data type settings that control how the print job is formatted before transmission.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Examine the printer driver properties and advanced settings, such as print processor or default language
The issue is specific to network printing on one workstation, with USB printing working fine and other network users unaffected. This isolates the problem to the print processor or data format handling on that client. Reinstalling the driver didn't fix it, so the next step is to check the driver's advanced settings, such as the print processor (e.g., WinPrint vs. HP Standard) or the default data type (e.g., RAW vs. EMF), which can cause garbled output if mismatched with the printer's PDL interpretation.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Verify the printer's network configuration via its control panel
Why it's wrong here
Verifying the printer's network configuration via its control panel checks items like IP address, subnet mask, and gateway — attributes that determine whether the printer is reachable on the network. Because other users are successfully sending jobs to the printer, its network settings are clearly valid and the printer is reachable. The garbled text originates from how the workstation's driver formats data, not from the printer's network addressing or connection state. Therefore, checking the control panel would only confirm what is already working, and would not diagnose why one PC's output is corrupted.
When this WOULD be correct
If all users on the network were unable to print or experienced garbled text, verifying the printer's network configuration (e.g., IP address, subnet mask) would be appropriate to rule out misconfiguration.
- ✗
Check the network cable and switch port for the printer
Why it's wrong here
The network cable and switch port are shared infrastructure; if other users on the same printer can print correctly, the physical path from the printer to the network is intact. A faulty cable or port typically causes dropped packets, link-loss, or complete unavailability, not consistently garbled text on a single workstation. Even if a marginal cable corrupted some data, the printer would likely reject or misinterpret many jobs, affecting multiple users. Thus, inspecting the cable and switch port is a low-yield, incorrect step for a one-user driver-related problem.
When this WOULD be correct
If multiple users on the same network segment report printing issues or the printer is completely unreachable, checking the network cable and switch port would be appropriate to rule out physical connectivity problems.
- ✓
Examine the printer driver properties and advanced settings, such as print processor or default language
Why this is correct
Garbled output on only one workstation strongly points to a client-side driver configuration mismatch. The printer's default language setting (e.g., PCL vs. PostScript) tells the spooler which page description language to send; selecting the wrong one causes the printer to interpret control commands as literal text, yielding gibberish. Similarly, the print processor (such as WinPrint vs. a vendor-specific processor) handles spool file data — an incorrect setting can pass binary or unformatted data to the printer. Reinstalling the driver with the correct options or adjusting these advanced settings is the proper fix.
- ✗
Update the firmware on the network printer
Why it's wrong here
Firmware updates address defects and feature gaps in the printer's embedded software, not client-side driver misconfigurations. Since all other users print correctly, the printer's firmware is already functioning properly for jobs being sent to it. Updating firmware is a broad, disruptive action that could potentially reset printer settings or introduce new issues, and it cannot fix a driver option like default language or print processor that is set incorrectly on one PC. This measure is only relevant when the problem affects all users, not a single workstation.
When this WOULD be correct
If multiple users on the same network experience garbled text or other printing issues, and driver reinstallation does not resolve it, updating the printer firmware might fix compatibility or protocol bugs.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 220-1101 exam frequently reuses these exact scenarios with slightly different constraints.

✗Verify the printer's network configuration via its control panelWrong answer — click to see why▾
Why this is wrong here
The issue is isolated to one user over Ethernet, while USB works and other users print fine. This points to a client-side configuration problem, not the printer's network settings.
★ When this WOULD be the correct answer
If all users on the network were unable to print or experienced garbled text, verifying the printer's network configuration (e.g., IP address, subnet mask) would be appropriate to rule out misconfiguration.
Why candidates choose this
Candidates may assume garbled text is a network issue and jump to checking the printer's network settings, overlooking that the problem is specific to one user's print driver configuration.
✗Check the network cable and switch port for the printerWrong answer — click to see why▾
Why this is wrong here
Other users on the same network can print correctly, so the printer's network connectivity is fine. The issue is isolated to one user, indicating a client-side configuration problem rather than a network infrastructure issue.
★ When this WOULD be the correct answer
If multiple users on the same network segment report printing issues or the printer is completely unreachable, checking the network cable and switch port would be appropriate to rule out physical connectivity problems.
Why candidates choose this
Candidates may assume garbled output is due to network interference or cable faults, overlooking that the problem is user-specific and the network path is working for others.
✗Update the firmware on the network printerWrong answer — click to see why▾
Why this is wrong here
The user can print correctly via USB, and other users print fine over the network, indicating the printer's firmware is not the issue. The problem is specific to this user's network printing configuration, not the printer's firmware.
★ When this WOULD be the correct answer
If multiple users on the same network experience garbled text or other printing issues, and driver reinstallation does not resolve it, updating the printer firmware might fix compatibility or protocol bugs.
Why candidates choose this
Candidates may think firmware updates resolve many printing issues, overlooking that the problem is isolated to one user's network printing setup.
