Never use a low quality printer to type your resume. It's very important that you make sure the writing on your resume looks good. This means clean, crisp, and sharp looking letters. A third aspect of your resume's appearance is more subjective. It takes into account such things as the letter spacing, how each section is arranged, and it's overall appearance.
Some resumes simply look better because of the way they have been designed.
At the end of this report, you'll see an example of a properly prepared resume. Never overcrowd the resume. Never submit a resume with handwritten corrections. If possible, use larger letters for the headings used in the separate sections of the resume. Never try to be too fancy by using wild colors, cute graphics, and so forth.
