Used for Trouble: T-000036

1) Confirm multi-printer impact

• Identify which printers fail when others are active
• Note whether failures are simultaneous or sequential
• Confirm issue does not occur with a single active printer

2) Check print spooler contention

• Open printer queues for all printers
• Observe queue behavior during concurrent printing
• Restart Print Spooler to clear stalled jobs

3) Verify application concurrent print handling

• Confirm POS / CSC supports multiple simultaneous printers
• Check configuration for serial vs parallel printing
• Avoid shared or fallback printer definitions

4) Inspect network capacity

• Verify printers are not sharing a saturated network segment
• Check switch performance and cabling
• Move printers to dedicated ports if possible

5) Avoid shared USB hubs

• Connect USB printers directly to system
• Remove intermediate hubs or splitters
• Test printing again with direct connections

6) Check driver conflicts

• Ensure each printer uses the correct driver
• Avoid mixing incompatible drivers
• Reinstall drivers if conflicts are suspected

7) Test controlled simultaneous printing

• Send test orders to multiple printers at once
• Observe whether all printers complete successfully
• Repeat under moderate load

8) Escalation check

• If failures persist:
• Capture which printers fail and when
• Review application logs
• Escalate to application or systems support
