Note: I have gone thru a half dozen Canon printers but this Panasonic dot matrix printer seems to last forever. The cartridge lasts a lot longer also.
Furthermore, new printers won't print from DOS.

since that appears to be a printout from windows, why don't you just do a screen capture instead of printing and scanning?

Good suggestion. I had not taken the time to figure out how to do it but I see that if it is saved as a .gif, it is only 27K in size.

just press the "print screen" button on your keyboard, and then open up an image editor (MS paint works fine) and just paste the image (CTRL+V) and save it as whatever format you wish.

Thanks, I will try that. I didn't think print screen key worked any more.

On my old pc I had to press another key with Prt Scrn to make it work. Shift, Ctrl or Alt.
In MS Paint, click Edit at the top then you are allowed to Paste the remembered image.

Under Windows it copies the screen to the clipboard, you can then paste it into Windows Paint.

Thanks, all. I will be computer literate one of these days.

Hey Russ,
You are a lot more computer-literate than me! :lol:
I was using a 486 pc for more than 10 years until 11 months ago, have been making schematics in MS-Paint for 2 years and just started doing Spice-sims this month.
