Ok, I installed Dipstrace just to help you out since you're getting nowhere extremely slowly.
As the Dipstrace forum stated, you have the option to save an image from the print preview screen. There are a number of options on that screen. If you had taken the trouble to give this a few seconds of thought, this thread probably wouldn't be on 5 pages now.
1. Save as BMP or JPG. Audioguru's concerns instantly answered.
2. Area: object or page. If no objects are highlighted, the image will be of the occupied area of the page. If page is selected, you get the entire page.
3. Scale Percentage - how much the image is magnified. The box is followed by the image size in pixels. With the schematic I have, 100% yields an image size of 225 x 230. Your computer screen is at least 800 pixels wide. An image of 225 pixels doesn't have enough detail to show text clearly. A scale of 500% gives me an image of about 1000 x 1000 pixels. Now the image is legible. Yes, it's numbers and yes, we know your mind turns off when it sees a number, but this isn't rocket science.
So....when you have the schematic complete, go to print preview, click SAVE, select JPEG or BMP (I think JPG will work fine as long as the resolution is high enough and the resulting file size will be less) and adjust the magnification to get an adequate drawing size (800 wide as a minimum, more if the schematic is detailed) and click ok.
When you make a post, look at the file once it's posted. If YOU can't read it easily, delete it and save it in a larger size. If you can't read it, don't expect anybody else to make the effort to do so.
