Parallel Ports vs. Trashing Printers

Recently bought 3 new workstations:  2 w/Windows 7 - - 1 w/Windows XP Pro... Question is:  my old HP Laserjet 2100tn will not work with these computers due to their not being a paralel port on the back of the computer.  
Do they make converters for the cables to make them work? Or is the printer basically worthless at this point?
This question was solved.
View Solution.

You can purchase and install parallel port adapter cards and the printer will work. I can't specify which cards as you haven't stated what the specs are on your workstations. There are also usb to parallel port converter cables available.

  • Parallel Port & Printing

    Hi,
    I am new to ArchLinux and have been using Gentoo since qutie a while. After installing nearly everything I need I am now struggling with the printer setup. I guess this is due to a problem with my parallel port, cause it does not show up in the selection box of cups. I can choose serial and usb ports, but no parallel ports. I have installed some modules like
    lp & parport
    I also have cups running of course and it connects. My question is the kernel (2.6.4) must be compiled with support for the parallel port by default, right? At least after loading these modules it should work. What am I missing?
    Thanks already!!!

    Good advice!  Haven't solved it yet, but FWIW I can read the cups documentation.  So I set the log to debug mode and here it is: 
    This log content follows

  • Parallel Port Listener problem

    hello everyone,
    I have downloaded the javax.comm package and installed it as given in the installation instructions. I can print my files using the javax.comm classes. But i do not get the Parallel Port Event even if i register a listener.
    Also for all the methods such as is PrinterError(), isPrinterTimedOut(), isPaperOut() etc i do not get anything else but flase. Even if the printer is online or not, or if the paper is out etc, in all cases only false is returned by these methods. Please tel me what could be the problem.
    All these methods return false even when the printer is online or not :
    parallelPort.isPrinterBusy()
    parallelPort.isPrinterError()
    parallelPort.isPrinterSelected()parallelPort.isPrinterTimedOut()
    parallelPort.isPaperOut()

    Well, i think you should be looking for specs about the printer(s) to find out how they communicate with windows. That might not be that easy because not all company's will be very open about that. You should realise that any message windows gives you about the printerstatus comes to you via the drivers for that printer. The drivers know how to communicate with the printer, and that's different per printer.
    The most used standard for printing is Postscript (I believe HP6L is a postscript printer) wich is supported by the 'bigger' printers. There will be info about Postscript on the web, but it is owned by Adobe and I son't know how free the specs are...
    An older dot matrix printer is more likely to be using the lines that are signal out busy, error etc. You will find the pin layout here: http://www.doc.ic.ac.uk/~ih/doc/par/doc/regpins.html
    If all your after is printing your files you might want to use java.awt.PrintJob wich will let you print through the spooler of the operating system, thus letting the OS handle the printer with the right drivers.

  • Piping text to an ieee-1284 / centronics parallel port

    I want to send raw text to a parallel port (IEEE-1284) via a USB-parallel converter. I plug the converter in and the Mac recognizes it natively; it shows up in the list of printers in the System Profiler. How would I pipe text to the thing? With a serial device, it's easy, sending the text to the appropriate device in /dev/tty.*
    Any pointers would be greatly appreciated.

    I can't recall the last time I saw an Apple product that shipped with a parallel port, but I imagine its hard because there aren't enough people clamoring for 40 year old technology to justify maintaining support for it in modern source bases.
    You can find what driver is matching for the device in the IORegistry with the ioreg tool.

  • HP color laserjet 4600 parallel port is wierd need help to identify

    Hi I have a laserjet 4600 and it has a wierd looking parallel port and I can't seem to find out the name for it so I can buy it online. I have tried looking for it online but the only thing that comes up is the IEEE 1284 36 pin parallel port. Can anyone help me identify this port so I can connect it to my computer?
    Thanks

      Do I need to set up a network. I know the IP of the printer and can not access it from the Notebook.
    This should work for you.  I've installed several printers using a Jet Direct this way:
    Install the printer manually.  Go into Devices and Printers -> Click "Add a printer" then select "add a local printer" and select the option for "Create a new port - Standard TCP/IP Port" and click next.  Type the IP address of the printer into the Hostname/IP Address field then click "next" -  Choose Hewlett Packard Jet Direct from the Standard drop down menu then click next.  You will need to select your printer model/driver from the list and then click next.  

  • New workstation lacking parallel port poses printing challenge

    I'm supporting a Netware 4.11 + sp9 small business network, which long ago
    had a custom DOS-like database application written to manage rental
    activities. The app allows the user to print out lists of things rented,
    etc. It has been working very well for years. There are several
    workstations, some DOS, some Windows XP, etc., and they all share the rental
    database resident in the Netware 4.11 file server.
    I have had various networked printers, starting with parallel-port lasers.
    More recently I have had a large Canon printer that connects directly via
    our Ethernet_802.2 IPX (as well as IP) intranet. In other words, this
    printer works both for Windows programs, which use IP, and for our rental
    program, which uses IPX.
    What's the problem, then?
    An important Windows 2000 Pro workstation died, and I replaced it with a new
    Windows XP Pro workstation. This new Dell computer HAS NO PRINTER PORT. I
    have YET to tinker with this, as I am hoping to get this request for help
    posted as soon as possible.
    All my workstation computers "CAPTURE" print jobs that the rental program
    "thinks" are going to LPT ports. Once these jobs get into various queues, I
    have no problem getting them into printed hard copy. The problem NOW is to
    fool the DOS-like rental program, which will be running on the new Dell
    computer, into seeing some kind of a parallel port that doesn't exist.
    I suppose I could launch a major effort into modifying the BIOS of a Dell
    computer, but I am hoping there must be a better way!
    Can "net use" be of any assistance?
    Can Unix "lpt" printing be of any assistance?
    It is not likely this rental application can be chanaged. I am not the
    author.
    I read another thread regarding an "opposite" predicament. It won't help
    me, then, to buy a USB->LPT adapter box, because what's important here is
    NOT to actually connect a printer to this workstation computer, but to
    supply something (a faux LPT port) that can be captured inside this
    workstation.
    Any ideas most welcome.
    Thank you.
    John B

    This is neat. But I think the all-important DOS-like custom application
    rigidly prints only to LPT1.
    In the absence of a real LPT1, I need to find a "faux LPT1."
    Over the weekend, I'll look at this utility..."printfil."
    Thanks very much!

  • RXTX Parallel port communication with Pin Printer

    I have successfully installed and configured RXTX-2.0-7pre1 on Linux platform.
    2 printers, one Laser jet printer connected to the Serial port and the other Pin Printer connected to the Parallel port.
    I can print my files out successfully with RXTX on both my 2 printers. But, there is some problem with my Pin Printer performance. The print job is a little slow and the printing is word by word output.
    While the Laser printer received the whole string of my RXTX output and printed them out asap.
    RXTX read my data and write them to the Parallel/Serial port directly, so, for my laser jet printer, it buffered the RXTX output data and processed them all in one. No problem, laser printer works well. But to the Pin Printer, it got the RXTX output and printed them out with no buffer. I am not authorized to deal with the Pin Printer device driver.
    So, my question is that, is there someone knows how to resolve this problem on RXTX side? That is to say, how to modify the source code of RXTX and customize it?
    I wanna know how to create buffer in RXTX, for example, buffering a whole string line and then sending them to the Parallel port. Then, It supposed to be that the Pin Printer will receive once a whole line output and printing line by line in the paper! Not the problemly slowly word by word output!
    Thanks a lot!

    Simple metrics from google should suffice the SUN team from understand the need/huge requirement for supporting Serial and parallel port programming in windows. Platforms would always change and the team at SUN should remain commited in supporting new platforms.

  • Control parallel port (data and control lines)

    I need to control the output on the parallel port (LPT1) - Both data and control lines.  Once the data is written (Pins2-9), I then need to toggle the Sprocket signal (PIN1) - on the parallel port. The sprocket signal is also referred to as the Data Strobe Output.
    The required method is as follows:
    1. Lower the sprocket signal on PIN1
    2. Send the data (Pins2-9) and wait
    3. Raise the sprocket signal and wait.
    4. Repeat.
    I am looking for a method to control the data on LPT1 pins 2-9 and then be able to toggle PIN1 - Strobe signal - without the data falling from the other pins. What I have found is that whenever the state is changed on the strobe - the data that was written to Pin2-9 falls to zero. This will not work for my application - the strobe tells the hardware device that the data is ready. If it falls to zero when I toggle the strobe - that will not work.
    Regards,
    Guy

    Hello Adam,
    I am familiar with both references.  If you look more closely at the library reference - it allows me to communicate using VISA across the parallel port pins 2-9.  It does not permit direct communication to pin1 (the strobe signal) - property nodes don't allow the strobe to be refereced either (similar to control lines/signals for COM ports).
    Worse, I have also located examples using OUT PORT that does enable pin1 to be toggled.  The problem is, when those VIs are used, the data falls from the data pins when the strobe signal is written, even if its value is not changed.  For example, if the strobe is already high, if another high value is passed, the data falls from the data lines.  The other issue, when using VISA, as soon as the data is writen, the strobe signal automatically goes high even though I need a wait before setting the strobe high.  This is in complete contradiction to the second article you referenced which clearly discusses writing data to pins2-9 then taking the strobe high to indicate to the printer that new data is available.  It must be possible since this is the typical handshake.
    I am still looking for a more complete answer/solution.
    Regards,
    Guy

  • How can I write to the parallel port using LabVIEW 6.0.2

    I have tried updating the labview.ini file and also using the parallel.llb available on the site. When I execute the program it gives me error 37 saying,"device not found". I am running this code on windows 98. I tried to use VISA write,serial port write (using port 10) but nothing seems to work. I also tried to develop a sample code using inPort and outPort, but no success, it is not able to read the data back from the parallel port, even if it seems (????i don't know any way to cross-check it though????) to write.
    Does anybody know the problem here?
    THanks.
    Pari.

    Thanks Brian.
    Well here is the next problem. I got a VI (attatched) off ni.com and it works fine on a windows98 platform. But quits working on NT.
    I can write perfectly (which i checked by hooking an LED display unit at the other end of the parallel port cable). I observed that the LEDs respond to the toggling of individual bits (data bits). But the error occures at the "out port.vi", when I try to run it on a NT machine (where I actually wanna use it). Are you aware of any changes to be made in order to run a VI on NT that works on 98?
    Thanks again.

  • How to Install a parallel port printer to usb port of Pavilion dv5 Notebook

    In trying to install my HP DeskJet 610C Parallel Port printer to my HP Pavilion dv5-1235dx Notebook PC with Windows Vista Home Premium 64-bit, I followed instructions given by HP Support some two years back.
    I connected up the two units through a Parallel-to-USB ports cable. The PC loaded and confirmed suitable driver. (Following advice from sites on the Internet, I have made repeated attempts to carefully install the printer, but to no avail).
    Upon my issuing the Print instruction, the printer invariably prints two copies of what appears to be 'gibberish' in two lines at the start of the sheet. Thereafter it picks up and then ejects 6-8 sheets of blank paper.
    Any help in resolving this anomalous situation will be be most welcome and much appreciated.
    I might add that the printer works normally when connected in parallel to an older, Compaq Armada 1750 Notebook (XP OS). In this instance too, the Parrallel/USB worked as in the Pavilion PC, above.  
    This question was solved.

    Please help...  Looking to have my parallel port dongle recognized for my older version software (XP) in Windows 7 under the XP PC mode.  Help in figuring out if LPT1 is set correctly or what I am doing wrong.
    Thanks

    Hello,
    I have W7 Professional 64 bit with Windows Virtual PC/Windows XP Mode installed. I have some older programs installed in XP Mode and they are working properly.
    Unfortunately, I have one older program that I currently have working on an older XP Machine and that program requires a Sentinel dongle to be seen on the LPT1 Parallel Port. Since my W7 computer has an LPT1 Header on the mother board, I have purchased and
    installed a PCI-Express Parallel Port and I have the ribbon cable connected to the LPT1 Header.
    After I enabled the parallel port in the bios, I could see LPT1 in the W7 Device Manager and in the Windows XP Mode Device Manager. However, when I click on
    Windows Virtual PC, highlight Windows XP Mode.vmcx and click on Settings, LPT1 does not appear.
    I have installed my old program in Windows XP Mode and it starts to run but, when it gets to the point where it must see the Sentinel dongle on the LPT1, the
    program does not find the dongle.
    I also purchased a Manhattan MHUSB to DB25 Parallel Converter and plugged it in. It said that it found new hardware and installed drivers for it but that didn’t
    work either.
    I am not married to any particular solution. So, I would use a USB Adapter or LPT1 connected to the mother board but there must be some code editing or changes
    in settings to make the dongle work in XP Mode.
    Can you tell me how to get W7 Professional 64 bit with Windows Virtual PC/Windows XP Mode to find the Sentinel dongle 
    on LPT1?
    Thank you,
    Dan
