How to Change the Font for a Dot Matrix Printer

Check your printer for a ��Quality�� or ��Speed�� button. You can find this on your printer��s control panel, usually on the top or front of the printer.
Choose a different quality or speed. When you choose a different quality or speed on a dot matrix printer, the printer will change to a different font to accommodate your request.
Use the ��Quality�� or ��Speed�� button to change the font for an entire document, before you begin printing. Each keypress will cycle you through the available fonts.



Consult your printer manual to determine if it will respond to invisible ��printer codes�� which you can embed in your document. A printer code will not print a character, but will change the font for subsequent characters. If you do not have the manual, check the manufacturer��s website. If the manufacturer's website cannot be found, or if they do not list their dot matrix printers, perform an Internet search for the exact make and model; some websites have posted manuals for older printers which are no longer being made.
Write these codes into your document to change fonts on the fly in the middle of your document. If your word processor will not let you embed printer codes, use a programmer��s text editor, which will allow inclusion of invisible characters.
Print the document to confirm that your printer codes are working properly.
