Hello Edgar,
Thanks for your post!
I’m sorry to respond delay due to the weekend.
For this issue, please try the following steps to confirm whether it’s caused by spooler issue:
1. When the problem occurs, end the spooler.
Right-click Command Prompt and select Run as Administrator. Input the command net stop spooler, press Enter.
2. Try to clear the printing job again. If it does, enable spooler again by the method below:
Right-click Command Prompt and select Run as Administrator. Input the command net start spooler, press Enter.
If the problem is caused by spooler, please make sure whether the printers are using the latest drivers designed for Windows Vista.
Please let me know the result and the models of involved printers also.
Thanks!
Regards,
Lionel Chen
