Assuming the printer is connected to a computer "ServerName", and it's available using a share name "MatrixPrinter", then on your workstation you can redirect your LPTn printer port to that share:

REM From a CMD prompt run
NET USE LPTn \\ServerName\MatrixPrinter /persistent:y

Also, depending on how print jobs are spooled you may notice a 15 second delay between your COPY command and the start of the print job. This can be reduced by adjusting a registry key LPT_timeout: https://technet.microsoft.com/en-us/library/cc959496.aspx . These days, with fast computers 2 seconds is probably a safe value.
