Need Help Hp latex 115 printing problems

[JoshGS]

Hi all can someone please help me work out that is going on with my printer I have changed the encoder strip replaced the belt I have done a manual print head alignment
Every thing looks fine

When I print the internal print to see what is going on with the printer it prints perfectly I will attach a photo

So I draw my work up in Illistrator and expand all text to a vector line save the file to a usb plug it into my windows laptop for the printer and print it off Any time I print from production manager if it is a straight line both horizontally and vertically it will print fine but if the line is curved, it will not print a perfect line. The curve call Look stepped

Please if any one knows of a setting maybe I can change I just don’t get why the internal print is fine and anything from my computer it looks horrible

Check the resolution of the raster file that the RIP software is set to generate. I generally use 600 dpi (should really read ppi) for everything sent from the RIP.

The one setting that I have over looked for some reason it have switched to 150x150 I do have a question I am printing on Hp everyday satin photo paper the max resolution is 300x300 how can I change that to 600x600 when that option isn’t available
