LPT1 is a port found on older computers and some newer ones that you can connect a printer to. This port is a female connector with 25 pinholes.

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.

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

Printout of output in c plus plus?

To print the output of a C++ console program (or indeed any console program), redirect the output to a file then print the file. If you have a line printer attached to LPT1, redirect to LPT1. Redirection is achieved from the command line. Redirection does not affect error output (std::cerr), only standard output (std::cout).

How do you print the output of a c plus plus program?

You print the output of a C++ console program by redirecting the output to the appropriate output stream (display, printer or file). This is achieved via the command line. For example: progname >> LPT1 In this case, all output that is directed to stdout (which defaults to the display device) will be redirected to the device associated with LPT1 instead. Output that is directed to stderr will not be affected, so errors will be directed to the default stderr device (usually the display device).

How do you get DOS mode printout from a dot matrix printer using USB to parallel converter in Windows mode?

Your question has alot of variables. When you say "dos mode printout", I assume you mean an old DOS application that is printing directly to LPT1. This can also be simulated by opening a command prompt and copying a small text file to lpt1. c:\>COPY TEST.TXT LPT1 I assume your new computer does not have a LPT1 port so you bought a USB to parallel converter to continue to use your old parallel printer. The first suggestion is to share your printer and record the share name. Go to control panel, printers, right click the icon for the printer you are using, click properties, then sharing, then share the printer. Record the share name, for example BROTHERM or HPLASERJ. Note that most people use 8 characters or less for this name for maximum compatibility across operating systems. Now go to control panel, system, Computer Name and record the "full computer name" of your computer. Note that most people also use 8 characters or less for this name for maximum compatibility across operating systems. For example it might be "office" or "dell1234". The period at the end is not part of the "full computer name". Now you can go to a command prompt by clicking on Start, All Programs, Accessories, Command Prompt. Enter this net use command with your computer name and printer share name: net use lpt1: \\computer\share example: c:\>net use lpt1: \\office\hplaserj c:\>net use lpt1: \\dell1234\brotherm check the status of the command be entering the command: c:\>net use There is only a 80% chance this solution will work. I do not know the details of your USB to parallel converter. I do not know the details of your printer. Your printer needs to support "character mode printing". Most parallel printers DO support "character mode printing". There is no industry standard terminology for this printing mode. You could ask "Does the printer support DOS mode printing?" Most network printers do support this character mode printing. Unfortunately this specific specification if often not listed on the outside of the box or on the manufacturer's web site. In your case, my second suggestion would be to discard the USB to parallel converter and instead have a technician install a parallel printer port inside your computer. The printer port will only cost about $15 dollars and the technician will charge you more than that to install it. Then you will have a real LPT1 and you can hook your old parallel port printer directly to this real hardware parallel port. Then there is no conversion or net use command. I assume your old printer has worked in character mode before so you should be 100% guaranteed that this will solve your problem. My third suggestion would be to install a third party software solution. I call these third party because it is not your DOS application, it is not Microsoft Windows, but a third company that has solved your DOS to printer problem. I do not know of any FREE solutions. Most are shareware and cost around $20. There will be minimal download, install, and setup required. Most let you test them out for 100 pages of printout or 30 days in shareware mode to make sure they work before you buy them. This solution will not require that you share your printer or issue any NET USE commands. This solution should be 100% guaranteed since these third party utilities were designed specifically to solve this problem. DOSprn is one such utility that I have seen work. Here are some example printers and solutions that have been used to print from DOS applications that print to LPT1. Lexmark 2490 printer supports USB and parallel port installation. If you have one of these, I'd hook it up to a real hardware LPT1 port and it will work great. Epson LQ570E printer supports USB and parallel port installation. If you have one of these, I'd hook it up to a real hardware LPT1 port and it will work great. HP LaserJet P3005 printer supports USB and parallel port installation. If you have one of these, I'd hook it up to a real hardware LPT1 port and it will work great. HP InkJet HP6940 printer supports USB only. If you have one of these, I'd share it and use the NET USE lpt1: solution to use it. Brother MFC-7420 printer supports USB and parallel port installation. Unfortunately, this printer does not print in character mode even when it is hooked to a real hardware parallel port. The NET USE LPT1: solution will not work. If you have one of these, you will need to get a different printer or use one of the shareware print utilities like DOSprn.

If a sound card operates correctly except when a printing operation is in progress what is most likely the problem?

This problem won't be found in any relatively modern computer. On a much older system, it would indicate that the sound card and LPT1 were sharing the same IRQ.

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.

What is the name of the 25-pin connector located in the back of a computer?
