Tip & How-To about Office Equipment & Supplies
If your printer is connected to your computer via a parallel port (or LPT), it can use 100% of your processor time for your prints. In some cases, other open programs do not meet longer during printing.
This issue is related to the parallel port which is connected to your printer. Windows does not support interrupts on the parallel port which leads him to use 100% of your CPU to your impressions.
The only workaround for this problem is to abandon the parallel port to connect your printer to your PC and instead use the USB port. We must make sure your printer supports this connection type.
