Linux Easter Egg - Printer on Fire!

1. Using LINUX 2.2.1 (havent checked others), with bidirectional printer support
2. Print from the network and force a printer jam (tear a corner off a piece of paper and put back into th printer)
3. Issue a print command
4. Watch the output of the console (says lp0 printer on fire!)
5. Should have seen me RUN to the printer

I've seen this one, got a hearty laugh, but... Can open source software really have eggs? /usr/src/linux/drivers/char/lp.c: static int lp_check_status(int minor) { unsigned int last = lp_table[minor].last_error; unsigned char status = r_str(minor); if ((status & LP_PERRORP) && !(LP_F(minor) & LP_CAREFUL)) /* No error. */ last = 0; else if ((status & LP_POUTPA)) { if (last != LP_POUTPA) { last = LP_POUTPA; printk(KERN_INFO "lp%d out of paper\n", minor); } } else if (!(status & LP_PSELECD)) { if (last != LP_PSELECD) { last = LP_PSELECD; printk(KERN_INFO "lp%d off-line\n", minor); } } else if (!(status & LP_PERRORP)) { if (last != LP_PERRORP) { last = LP_PERRORP; printk(KERN_INFO "lp%d on fire\n", minor); } } else { last = 0; /* Come here if LP_CAREFUL is set and no errors are reported. */ } lp_table[minor].last_error = last; if (last != 0) { if (LP_F(minor) & LP_ABORT) return 1; lp_error(minor); } return 0; }
