Totally different class of demon there. Spellcheckers are the ghosts of failed creatives past, bent on crushing individuality and innovation. The demonic school marm.
Printer demons are something else entirely. Purest evil, they can inhale great gouts of expensive ink while sounding like a poorly maintained 1970s Pinto on a hill. Using some sort of hellish logic, they always fail just when the important stuff must be printed. They are unfixable and further printing can only be done by selling another piece of oneās essence to Lord Canon or Prince Epson (little brothers to Mammon and Creosus). Printers are fucking evil monstrous things and should probably be doused in holy water as a matter of course.
