How Can you access Parallel Port using c plus plus?
You cannot directly access the parallel port because the operating system is managing that device. Use the file system. The name of the parallel port is "lpt1:". Open that as an ordinary file for write, write to it, and you will be writing on the parallel port.
Printout of output in c plus plus?
This question could mean one of two things: either the program should print its machine code, or it should print its source code. Printing the machine code is easy enough since the first argument passed to the program contains the executable name. So you simply need to open this file as a binary input file and redirect the content to std::cout. Some characters will be non-printable of course, so it might be better to convert every byte to its hexadecimal equivalent and print that instead. A machine code program that prints its own source is somewhat more complex. Firstly, you need to know which file or files to print. If the source code is contained in a single source file then it's relatively simple to print the one file provided you tell the program which file to print. Using the executable file name to derive the source code file name is one possibility. And if the source has a header this could also be derived. If the program source is spread over multiple sources with many includes then you should locate the project file that lists all the files used by the project and parse this file in order to obtain each file name you need to print. You can safely ignore standard library includes and binary library links since you'd only be interested in your own user-defined files. Ideally these will all be placed in the same folder so they'll be easy to identify. You might also have re-usable code modules in other folders but if they're all within the same folder hierarchy they should be easy to identify as well. Once you have a list of all the project files files you can go ahead and print them.

What is an LPT1 on a computer?
It is a device file used for Parallel port. Consider the following command dir >prn (or) lpt1 dir >com1 dir >com2 that is the input is sent to the specified device file or device or a file.
Is there a way to remap the lpt1 port to a usb port on a laptop running XP home so that a DOS version of SuperCalc can be used?
First, a USB to LPT1 adaptor will not work, because DOS doesn't know that USB exist. My research finds that a PMCIA or express to LPT1 adapter may be your only salvation, just be careful to select one that fully works with output in both print directions.
What port transmits data in parallel and is most ofen used by a printer?
A Parallel Port (LPT1 and LPT2)
Can LPT Port be used as COM Port?
MODE LPTx=COMx Unfortunately MODE LPTx:=COMx redirects parallel printer output to a COMport, I've never seen any indication that it will work the other way. For example, to accommodate a 1200 baud serial printer on COM2 to a program that only has LPT1 output: MODE COM2:1200,n,8,1,p sets up the comport with continuous retry MODE LPT1:=COM2 redirects LPT1 output to COM2
