The predecessors to word-processing computers and word-processing applications within modern desktop computers, typewriters were among the first devices that allowed people to compose documents without having to write freehand. Of course, typewriters weren't without their limitations: in addition to the fact that special characters and variations in font and size were limited and, in many cases nonexistent, typewriters don't have a "delete" function -- if you make a mistake, you must either start over or white it out. Given that limitation, lacking a typewriter when you need to fill out a form is not only inconsequential -- it might actually be beneficial.
Fill out your form the old-fashioned way, using a pen or pencil. As long as your handwriting is legible and you use a standard color ink (usually blue or black) to fill out the form, you will not experience any complications filling out your form freehand in lieu of typing.
Complete your form electronically using your computer. Ask the business or individual who sent you the form to send it to you electronically in editable PDF format (or, alternatively, in a word-processing document format such as Word, WordPerfect or OpenOffice), and fill in the form accordingly.
Print out the form you completed electronically if you must add your written signature in order to finalize it. Check the form before you sign it to make sure you haven't made any errors and that you agree with any terms and conditions it stipulates.
