If you work in Black and White then I [ ] Rasterize page is going to have some downfalls unless you choose a high DPI to send the job at....as devices can print solid colors at their native resolution (eg. 1200 dpi) then going at 300 dpi could make things look a little chunky compartively.
Let me offer this if you feel like geeking out with your designs....if you're printing to a non postscript printer, a PS printer or exporting to Acrobat 4 compatibility mode, stuff is getting rasterized in the background as those formats cannot support transparency....we don't expose that in the UI as it's kinda techie for folks (unless you have a good understanding of pre-press and work in halftones/linescreens)
To make things print faster to these types of devices I would suggest structuring the document as follows (if possible)....
- for things with gradients, halftones, transparency keep them on bottom layers
- for all things vector, that are 100% of a color (like black, cyan..) keep them on upper layers
...before printing conver the bottom layers to bitmaps, 300 dpi and leave that top layers as vectors so they will be printed at the device resolution....
..the easier route is to up the [ ] Rasterize this page resolution and let her fly.
