If you have a HP printer, you might notice that it mysteriously turns off at seemingly arbitrary intervals. Sometimes, even when there hasn’t been any paper loading or no printing for about 15 minutes, the print head gets really hot and shuts down Turning off an HP printer quickly will also prevent overheating at this stage. You can see this by looking at the printer’s power LED on its side: If it lights up red, then the head is not ready to go or if it lights up green, then it’s ready and you don’t have to move a muscle.
If you have an HP printer, the print head will cool down automatically after a while. You don’t have any choice about this part of the process even if you turn off the power manually by unplugging the printer’s power cord from its wall outlet. Your utility software (e.g., hard disk defragmenter) may need a little while to finish its house cleaning chores.Įven if you do not use your printer for a long time, data go stale in the print head, and the print head must cool down before it can be used again. Your anti-malware software may need to perform some scanning first. Your security software may take a while to sign off, and the time required varies from one security suite to another. Here are the things that happen to slow printing down when you turn off an inkjet printer: Since the printer cannot control its own behavior on its own, it relies on the PC to tell it what to do. It’s designed to allow only 1 USB device (your PC) to play havoc in your printer’s hub. The printer’s PC-to-printer data transmission is governed by a special chip called a Universal Serial Bus (USB) Hub.
That’s because of all the fancy features HP printer have, such as scanning and copying capabilities, a “smart” OS that can show you status updates on its LCD display panel, and even built-in wireless connectivity - features that are way beyond what most office printers offer.
When you turn off your inkjet printer, your PC also has to send data downstream to the printer which means that it’s not just a one-way street.
