PowerPoint 100% CPU

By klh456 ·
A user was trying to print one slide from PowerPoint. Powerpoint.exe started taking 100% of the CPU. We tried to end the process but could not. The Application was no longer running but the process was.

This is PowerPoint 2000 on a WINXP computer.

Anyone know what may have caused this and how it can be fixed if it happens again?

i found this searching the knowledgebase at article 318273
100 Percent CPU Usage Occurs When You Print on an LPT Printer Port

This article was previously published under Q318273
When you print on an LPT printer port, 100 percent CPU usage occurs until the print job is completed. This slows down other programs until the print job is completed. In some case, other programs may slow down enough that they seem completely unresponsive. This behavior affects all power users who have many programs running at one time.
This behavior occurs because Windows does not have interrupt support for LPT printers.
To work around this behavior, print to a Universal Serial Bus (USB) printer port. If the printer does not have this capability, use a parallel-USB cable.
This behavior is by design.

Thanks, he was printing to his LPT1 port so sounds like this is the answer.
