Problems with Tally Printers using Parallel interfaces with Personal Computers


It has been observed that some printers' interfaces benefit from the disabling of Windows LPT1 ECP Printer Port settings within Windows.  Usually setting the LPT1 port parameters in the Windows Control Panel is sufficient to allow the printer/PC/Laptop interfaces to communicate.    

  • Click on START, SETTINGS, CONTROL PANEL. 
  • In Control Panel double click on System. 
  • In System Properties select 'Device Manager' Tab, this is located at the top of the screen.
  • Now Double Click on Ports (COM & LPT). 
  • Double click on ECP Printer port.
  • Now select the 'Driver' Tab at the top of this window.

In the bottom of this window you will see one of two possible selections depending on the version of Windows that you have.

Windows 95 Operating System Release 1. 

  • For this version of Windows you will see Change Driver Button.
  • Click on Change Driver.
  • A select Device screen will appear. 
  • Now click the 'Show All Devices' Radio Button.
  • Now click and highlight 'Printer Port' and click on OK.
  • Click on OK.
  • You may need the Windows 95 CD-ROM, Windows will prompt you for this Disk.
  • The new port type will now be setup.
  • Restart Windows.

Windows 95 Operating System Release 2 and Windows 98 

  • In this version of the operating system you will see Update Driver
  • Click on Update Driver.
  • You will now get the Update Device Driver Wizard.
  • Click on the Radio Button for 'NO, Select Driver from List'. 
  • Click on NEXT.
  • Click the Radio Button for 'Show All Hardware'.
  • Select 'Printer Port'. 
  • Click on Finish.
  • Windows will now update the driver.
  • You May need your Windows 95 CD-ROM, Windows will prompt you for this Disk.
  • Restart Windows.

Occasionally, it has been found that in addition to the above setting the PC or Laptop Bios also requires modification.  If you have completed the above instructions and your printer still does not communicate correctly with Windows 95/98 please check your PC's Bios.  If you are unsure how to enter the Bios of your particular PC please consult your PC's User Manual.  Once into the Bios you should see settings for Printer Port or LPT1.  If the Bios LPT1 is set to ECP or EPP please change it to SPP (Standard PC Printer) or Output Only (especially when on a Compac PC).  Save and Exit.
