Geek spool amazement

So on my lurgi day, the print spooler runs out of space and the server borks. J Random User sent a 5Gb print job. I come in to a sea of "wah! I cannae print, captain!" calls blinking in merry red on my Big List Of Bad.

Surely, in this 'ere day and age of practically psychic paperclips and scary, scary clever tech, it's got to be possible to tell the print spooler "reject jobs if you don't have the space for 'em"?

Apparently not.
