Electric typewriters sometimes have devices for dealing with mistakes, such as one-line memory correction, or ribbons of correcting tape. However, they are not as "forgiving" as a word processor, where you can make hundreds of changes to a document before committing it to print. With an electric typewriter, if you spot a typing mistake only after you have typed several more lines on your document, you can't do much about it. With a word processor, you can do a spellcheck before printing.
New electric typewriters are not all that easy to find. While they were an improvement on manual typewriters in many ways, they had their heyday before the appearance of word processors and personal computers, and there are few manufacturers nowadays. The world's largest office products company currently has only two electric typewriters for sale. Secondhand electric typewriters are easier to locate, but you may have to purchase one without the backing of a guarantee, which is risky.
Just as the models themselves are not easy to get hold of, so too is it difficult to find parts and accessories for them. Electric typewriters need ribbons, and virtually every model needs a slightly different kind. Trying to locate a ribbon for a particular model is extremely difficult and may prove to be a fruitless search. If you need replacement parts for your electric typewriter, you may find they are expensive to obtain because of their scarceness. Furthermore, you may require expert knowledge to fit them properly.
Electric typewriters can be noisy as the physical processes required to create the print require motion and impact from the printing head, carrier and daisy wheel. There are dozens of fonts installed on a typical personal computer, but electric typewriters often have only a few possible typefaces. If you accidentally lean on the keyboard, you can produce a lot of gibberish on the paper. If you do this on a word processor, you can readily delete your mistake by pressing the backspace key.
