Int 05  - Print Screen                                                     [B]

Desc:  dump the current text screen to the first printer

Notes: normally invoked by the INT 09 handler when PrtSc key is pressed, but
     may be invoked directly by applications
   byte at 0050h:0000h contains status used by default handler
     00h not active
     01h PrtSc in progress
     FFh last PrtSc encountered error
   default handler is at F000h:FF54h in IBM PC and 100%-compatible BIOSes
   since the BOUND instruction also calls INT 05h, but returns control
     to the BOUND instruction, a failed BOUND check will cause an infinite
     loop of PrtScreens unless the INT 05 handler is aware of the problem
     and checks whether the interrupt was invoked by a BOUND instruction
BUG:   some old BIOSes/applications appear to destroy BP on return
