Having problems with your InDesign documents getting stuck in print spooler limbo whenever you try to print them?

Try this: In the Print dialog, click the Graphics category on the left, and then in the Graphics settings panel on the right, change the default method of downloading your fonts to your printer from "Complete" to "Subset."

That one little maneuver fixes many a "low printer memory" problem that causes the endless spooling. If it fixes your problem, you should edit the Default setting for your Printer Styles (in ID 2) or Printer Presets (in ID CS) — access either under the program's File menu — so the Subset option is the new default from then on.
