I can't adjust the size of the letters on my laptop

you don't say what windows version you are using
windows 7
Click "start" type in 'font size ' left click "make text larger or smaller "
adjust and click "apply" and "OK"

You weren't specific on OS (windows XP/7/Mac OS/etc..)

Typically right clicking on the desktop, OR going to control-panel and Screen settings will allow you to adjust icon and test size to accomidate for your visual situation.

Please write me with your specifics if you need additional help.

Look in the control panel settings to adjust resolution to a size that fits your needs--

Start

Control Panel

Appearance

hold down the ctrl and - to make the letters small.

1. On the computer:
- go on Print Preview, if document looks normal go to step 2. If it's small in Preview, read on.
- make sure you are writing in a font of at least size 10
- make sure you don't have ticked "Shrink to fit", but adjust to 100%.
- size of the paper is printing preferences is set up to A4 or Letter, depending on your region
- there is a known issue with Outlook printing in small font, you need a hotfix for that

2. On the printer:
- You have to go into the menu of the printer and see if there is an option for the font, if there is increase the size of it
- In the menu, make sure the paper size is correct
- If none of these worked, you may want to reinstall the drivers of the printer
- If that does not work, you may have to put a new firmware on the printer. You can download drivers and firmware from manufacturer's website

Normally you have to change the font size from the program that you're running, like notepad, text document, Microsoft word, you have to adjust the setting yourself on how big you want the font to be.

If you are using windows Vista, you can just simply right click on the desktop and choose personalize... At the left of your view, you can see that the is the word for adjusting the font size ( DPI ).. You can enlarge it to 120 DPI or just customize your desired size... Normally, the default is 96 DPI... Remember... the effect only happens after you restart your computer... The picture below will guide you... Hope this method will also works in other windows such as XP or 7...

You likely have your resolution too high.  I prefer my resolution high but I can read small writing easily.   To change this right-click your desktop and choose personalize then display settings  adjust to a lower resolution but try to keep the aspect ratio similar to the ratio of the monitor you are using or the image will look squished.  once you have finalized your decision you will have to tweak it using the controls on your monitor to stretch the picture out to the edge of your monitor.    Also you can use the ease of access in the control panel for an on screen magnifier, or simply increase the font size in personalize (left column) adjust font size (DPI) (dots per inch)
