Leaving aside the outdated matrix printers, in this article we will separate the two most common types of printing: laser as well as inkjet (inkjet). We should also remember that almost all market printers have it waiting systems, that is, even if we leave them, electricity consumption will not be a problem since they enter their energy saving mode use is funny.
That said, let's go there.
Life printers
All inkjet printers have printed semiconductor headers. These heads tend to be the first piece that pushes the printer, but luckily most manufacturers put them in print boxes themselves, so every time we change these, we will change heads. In any case, save the printer
Regular cleaning and storing it on the printer is important to ensure that you continue to print with good quality for a long time. The difference between leaving or closing the printer is usually not overlooked in terms of power, but having "healthy" print heads and proper ink use, Manufacturers' recommendation to leave the printer on.
In this case, Laser printers are not affected as they do not contain liquid ink, but four toners contain powdered ink.
Also opening or closing the printer always shortens its life because every time we open it, an examination process is carried out that transports its internal organs, which produce a coating.
Use of Ink
During repair cycles (cleaning head, etc.), the printer uses ink, sometimes up to 20% of cartridge content, and given the cost it has, it's not something we want to do. Using ink to clean printed articles is important for the printer to last, but sometimes these maintenance cycles can occur more often than necessary.
Usually it depends on the individual manufacturer, but opening the printer is always applicable to the self-referencing process we mentioned earlier, and for this reason (reducing ink use) it is recommended that the printer be stored on it, because in this way we will reduce the number of maintenance cycles
In summary and although it does not seem to interfere, they do not produce it themselves we recommend that you do not close the printer even though we will be for a while without using it. However, it is good to do it from time to time so that these maintenance and diagnostic cycles take place (for something).
Some experts say that, even if we do not use a printer, it is best to print diagnostic paper at least once a month to spin rollers and, in the case of inkjet printers, make it rotate through the canals.
