I have used a number of roll your own versions to create a fretboard and then draw by hand or with other tools to make patterns for scales and arpeggios.
The most relevant things are set the guitar string size to progress from large to small, left to right, put the standard fretboard makers in the right place. However, the fastest thing I found was to locate a high resolution shot of a guitar fretboard via Google images. Download the image, then edited to tweak the brightness and contrast, crop as needed as offered under Microsoft Office Picture Manager. Under Paint, you can pull the image in from 'paste from' and then add the strings if these are missing in the photo.
Once there, you can copy the element several times to fill the page. Save this as your raw template. Then add markers for your scales or chords and save by scale name, such as E minor Pentatonic.
Here is one just using Microsoft Paint:
Here is an example as used with Microsoft Office Picture Manager and Paint.
Here is one with the E minor Pentatonic.
You can easily download these images by right clicking and select "save as"...
UPDATE (Append): If you have a decent digital camera, take a picture of your own fretboard, transfer to your computer and use what ever picture editor you have to crop and enhance. You won't have to draw the strings in and you are pretty much ready to have a template to start drawing your scales, or chords in.
