It's true, workgroup printers typically have disks so they can buffer
print and scan jobs and reorder them and other fancy features.  The
disks are pretty big, and I wouldn't count on your print job being
overwritten very soon.

On the other hand, there's an easy way to avoid this problem: use
a printer without a disk.  The cheap home printers don't have them.
