Rotating Objects/Strokes = wavy edges?

When I rotate a stroke or a filled shape, I am getting wavy edges. I've noticed that if it's at 0°, 330°, 300, 270° etc. it's fine but anything in between the said angles isn't working. It doesn't matter how thin or think my stroke or shape is. What am I doing wrong?

Here's a screenshot that shows my problem:

Your printer doesn't support PostScript.

And on screen the amount of jagginess depends on the angle of the stroke as well.

There's no need to worry about this. Except your printer.

Try and print this as a PDF from Acrobat.

Sorry I cannot see it

Does it happen if you change the screen rendering preview from GPU to CPU?

Yes, it does. It also shows up when I print it.
Here is another screenshot. Then stroke angled at 270° is fine and clean, and the one at 258° is "wavy" even pixelated?Screen Shot 2018-01-27 at 1.05.21 PM.png

Looks like normal screen rendering/anti-aliasing.

You won't see that anymore with the upcoming 8K or 16K or more K monitors …

"normal screen rendering/anti-aliasing" doesn't explain why it shows up when printed though, does it?

It's a hp Laserjet m1212nf mfp. I don't know anything about postscript. I am trying to figure out how to enable postscript, but not having much luck yet.

In the printing dialog box in Illustrator please check the "Output" section. Which options are there?

Ah oh... another problem here.

Does this mean that any digital copies of this logo, for web, will have the jagged, wavy lines? It looks great when saved as a PDF and printed, but if I save it as a jpg, png, etc. it is a problem on screen. Also, I make a habit of giving clients jpg, png, etc. and they will not be able to use them in this case. What can I do?

That's the nature of pixel images. There are pixels in them.

Yes, true. But I am working in Illustrator. Why is it that my vector image looks jagged and wavy, just on the two rotated lines, even when it's a vector image? This means that when I save it as a jpeg or png, it never even had a chance of appearing smooth, like the rest of the lines in my image are.

Okay, here is another clue. In this screenshot there are two lines that are coming into the frame from the top corners. These lines used to be strokes and I used "outline stroke" and then "expanded" them. They are at an angle, and there is no wavy-ness.

Then there are the inner lines. The one on the right is a stroke that has been outlined and expanded, in an attempt to make the wavy look go away. The center line on the left is a filled shape, that also appears wavy.

I realize that this looks subtle, but it is destroying a logo that I am working on.

And here is a (poor quality) photo of the printed version. But you can really see the problem here:

And please note, when these inner lines are straight, they are fine:

Which part of this situation applies to you? Are you printing, exporting as a raster file, viewing on screen in Illustrator, or something else?

Viewing on screen. I was thinking that maybe my 1920x1080 monitor might just be a little low res compared to Macs I have worked on, but I'm not sure. My issue is worse than what is shown in this thread but not as bad as pixel preview.
