P-000035-01 Prevent partial ticket printing during peak load

← Back

Used for Trouble: T-000035

1) Confirm issue occurs only under peak volume

  • Ask staff when problem appears
  • Compare behavior during slow vs busy periods
  • Verify full orders print correctly off-peak

2) Reduce ticket complexity

  • Disable logos or large graphics
  • Simplify ticket layout
  • Reduce excessive modifiers or formatting if possible

3) Check printer memory limitations

  • Review printer model specifications
  • Identify memory or buffer constraints
  • Replace with higher-capacity printer if needed

4) Inspect application buffering behavior

  • Review application print queue handling
  • Identify dropped or truncated jobs under load
  • Restart application services to clear queues

5) Monitor Windows Print Spooler

  • Observe spooler queue growth during rush
  • Restart spooler if queue stalls or backs up
  • Avoid manual reprints during congestion

6) Verify network stability during peak

  • Check for packet loss or latency spikes
  • Avoid shared or overloaded network segments
  • Move printer to dedicated switch port if possible

7) Test controlled peak simulation

  • Send multiple rapid test orders
  • Observe whether tickets print fully
  • Adjust settings incrementally and retest

8) Escalation check

  • If partial prints continue:
  • Capture sample incomplete tickets
  • Record order volume at time of failure
  • Escalate to application or hardware support
