A dot matrix printer is an impact form of document production. A sliding print head glides across the paper and an inked ribbon is forced against the paper to create the text or image. You can change the page dimensions that the dot matrix prints on easily. You can do this at the operating system level -- so all applications printing to that printer come out at the new size -- or for a single document.

    Operating system

  1. 1

    Click on the “Start” button. Select “Control Panel” from the right-hand menu. If you have Windows 8, drag your mouse to either the bottom left or bottom right corner of the screen to bring up the "Charms" bar. Select "Settings" then click on "Control Panel." With a Mac, click on the apple symbol on the top taskbar and select "System Preferences."

  2. 2

    Select “Printers” from the subsequent menu. It is usually listed under the “Hardware” heading (Windows). On a Mac, select "Print & Fax."

  3. 3

    Right-click on your dot matrix printer. Choose “Setup” from the drop-down menu. On a Mac, double-click on your printer to bring up the dialogue box.

  4. 4

    Navigate to the “Paper Size” box. There will be a drop-down menu of standard sizes -- such as A4, labels or letter sizes -- that you can choose if your document is of a standard size. Alternatively, click on “User Defined Size.”

  5. 5

    Enter the desired dimensions of your document. Click “OK” twice. Click on “Close.”


  1. 1

    Click on “File” in the top menu bar. Select “Printer Settings” (Windows) or "Page Setup" (Apple) from the drop-down menu.

  2. 2

    Select the dot matrix printer that you want to use. Double-click on it and then click on “Page Setup.”

  3. 3

    Click on “Paper Size.” Select the dimensions of your document, either from the standard sizes or entering your own figures. Click on “OK,” then click on “Close.” The document will print out at the new size, but if you open another document in the same or a different programme, you will need to repeat the above process to set the page length.

Tips and warnings

  • Remember to adjust the arms of the paper feeder on your printer to ensure the new paper size enters the machine straight.
  • Paper dimensions are typically calibrated in increments of 0.01 inches. If you select a paper size that does not fit this formula, you will get an error message.
