Programs to print a BLACK page to an HP LaserJet. I plan to move this to https://github.com/vossenjp/

C Source
#include<stdio.h>/* Program to print a BLACK page to an HP LaserJet */main()
{ /* begin of main */printf("\n\n\nBlack PC Computing October 1991");
printf("\n\nNow printing black page...\n");
fprintf(stdprn,"%c%s",'\33',"&l0E");
fprintf(stdprn,"%c%s",'\33',"&l0L");
fprintf(stdprn,"%c%s",'\33',"*p0x0Y");
fprintf(stdprn,"%c%s",'\33',"*c2400a3300B");
fprintf(stdprn,"%c%s",'\33',"*c0P");
fprintf(stdprn,"%c%s",'\33',"E");
} /* end of main */
