Software Drivers The eSATA port does not require a driver to function. Both SFF and CMT form factors of HP Compaq dc7900 Business PCs have an eSATA connector on.

To be clear serial ports are legacy devices and seldom used today. If not actually needed the lack of drivers for this specific device would have no effect on the system The specification also says nothing about a parallel port (Lpt1). Do you have an expansion card into which you plugging in the printer. The socket would not be in the main group of connectors but separate and in the vertical slots. Some port expansion cards had both Serial and parallel ports so this might be the missing driver.

If so you would need to identify what the card is and find the appropriate drivers. Unfortunately it is highly likely they would not be available for Windows 7. The spec of the Printer does not show USB so have you got a USB to Parallel converter, In which case that is going to need drivers itself. Venerable and functional it may be but the 710c is a very old printer and although it may work if set up right is not supported on Windows 7.
