The good news is YES, there is a solution!
One can connect the Beckman LS6500 (and/or an LS6000 with Serial# 7064XXXX or higher) to a Windows 10 or Windows 7 OS computer pre-loaded with data Beckman LS capture software. The data-capture software will allow storage of customer data directly to the computer hard disk. If the computer is networked, one can then access their data on a networked computer easily.
If a Beckman LS6500 user would like to completely get rid of the dot matrix printer, they can connect the LS counter to a computer with data capture software (https://serviceai.us/wysewinterm/laptop-computer-with-beckman-ls-data-capture-software), and then plug in a printer hardware emulator into the printer port in order to get rid of the dot matrix printer.
Important Note: The only caveat in removing the dot matrix printer altogether from the LS counter is that the Data Capture software only transfers user data to the computer. It does not transfer calibration data to the computer. Most customers anyway do not need this calibration data. Therefore, getting rid of the dot matrix printer is a possibility. Another advantage of using data capture software with the Beckman LS is that the user can collect and save all the data on to the computer hard disk, and take printouts on a printer that is networked or connected to this computer whenever they want to get a hard copy.
