Jagged Edges when Printing

[David269450069bs1]

I'm trying to print an illusttrator file on my new Canon Pro 1000 but my image ends up with a jagged edge. I came across the discussions here and saw that someone recommended a Postscript RIP called Print Fab. I downloaded it and it fixed the jagged edges but now I have lines in my image. Any help or advice to fix the jagged edges or lines would be much appreciated. 

I'm printing from Illustrator directly or from PDF files. All files are saved at 300 DPI with the highest quality allowed.

So one of them is printed in Illustrator, the other one in Acrobat?

Looks like your printer can't do PostScript.

Those were both printed from Illustrator. I've been trying to print from Illustrator and from PDFs to see if there was any difference and the only thing that I can see is a difference in the way they handle the color - another problem for another day. I just want to to fix the jagged problem

What do you mean when you say my printer can't do PostScript? Is that the PrintFab software I installed?

[Monika Gause]

PostScript is a page description language. And your printer seems to have issues rendering it. What about printing from Acrobat - does that work?

[David269450069bs1]

That did work! But why???

[Monika Gause]

THat works because Acrobat does its own interpretation and then sends the data to the printer.

Are your images vector or raster? If they are raster images then jaggedness could result if you enlarge them from their original size. You can tell if they're raster or not by viewing the file in the Outline mode (View>Outline). If the art is vector then it will be visible as outlines. If it is raster you will see nothing but empty boxes.

It's in vector. Should it be in raster? 

[Bill Silbert]

No. Vector does not pixelate. If, however you save it as anything other than .ai or pdf then it will become raster.

The problem is that your printer abviously does pixels better then vector artwork. So either you get a decent RIP that can send your artwork or you use Acrobat or you indeed rasterize the images and send pixels.
