Writing direct to printer

[jones172]

Dear Users,

I want to write directly to the printer, in case there is an infinite loop. To do this, I want to define a pointer

fp = fopen ("something_or_other", "w"

Question: What is the "something_or_other"? lpt doesn't seem to work, nor does lpt:, nor does lpt1: I am using Borland Turbo C and writing to a DOS prompt under Win 95.
Help appreciated.

fopen won't work on Win95 for devices. Have a look at

Basically it is for serial comms. All you need to do is to replace com1 with lpt1. You will need to #include <windows.h>. I know it is a DOS application you are working on but you will need <windows.h> for the prototypes of CreateFile, WriteFile and CloseHandle.

i don't know 'window', you should be able
to do this using 'popen()', see also my
sample-code in thread205-336551 (sending mail) change mail by the appropriate print
command.
