    ExpressPCB is free, and has a shorter learning curve than Eagle, if all you want to do are schematics. It does have the 89C51. It doesn't have the 74148, but it's very easy to create new components or modify the pinouts of similar, existing components in the library.

    Pull down menu at top left: FILE > PAGE SIZE > paper options.

    What I do is use:

    FILE>EXPORT SCHEMATIC IMAGE...>BIT MAP, 300 PIXELS PER INCH>your file name.

    I then use Microsoft Picture Manager to crop the BMP image and export it from there as a GIF file. You could use any graphics program that will accept a BMP file, let you edit and save it as a BMP, GIF, PNG, or JPG.

    On the full size schematic editor, if you don't use, or want the legend down in the lower right corner, just delete it. It gives you a little more room, if needed.
