You can decrease printing time by specifying driver compatibility for non-PostScript printing devices. For more information, see Printing colors accurately.
If a printing device has difficulty processing large bitmaps, you can divide a bitmap into smaller, more manageable chunks by setting an output threshold. If any lines appear when the printing device prints the chunks, you can set an overlap value to produce a seamless image.
To reduce file size, you can downsample images. Because images are made up of pixels, when you downsample an image, the number of pixels per line decreases, which decreases the file size.
