Program: PRINDIR is a shareware printer-redirection program by J.M. Allen
     Creations

Notes: the installation check consists of testing for the ASCIZ signature
     "PRINDIR N.NN" (where N.NN is the version number) two bytes beyond
     the start of the interrupt handler
   prior versions of PRINDIR used INT 7A instead of INT 7C
