Printing from Photoshop
When working with Photoshop, we recommend that you actually export to PDF and then print from Adobe Acrobat. Photoshop files are very large. Saving it as a PDF will compress your images and preserve crisp text.
In the File menu, select
Format to Photoshop PDF
Set Adobe PDF Preset to
[High Quality Print]
Uncheck Preserve Photoshop Editing Capabilities
Set Compatilibity to Acrobat 9/10 (PDF 1.7+)
Set Options to Bicubic Downsampling to 300ppi for images above 450ppi
Set Compression to JPEG
Set Image Quality to Maximum
Click Save PDF
Finally, see the Creating an Optimized PDF guide for final print output.
