The basic board spec shows it does not have a Serial port. However it does have an Intel Management Engine interface for which the drivers should be here.
If you read the driver page it informs that if these drivers are not installed it shows as missing drivers for a Simple Communications controller.
I am setting up a Optiplex 790 with windows xp sp3 and am having trouble finding a driver. Under the device manager, then under other devices, it shows PCI serial port with and exclamation point next to it. It is a new computer with an I5 in it. Thanks in advance. Hi, @GiuseppeP For the serial port, you need this driver. This package contains the Intel Management Engine Software version 11.0 for the supported Workstation models and operating systems. This package installs the latest Management Engine Interface (MEI) and Serial-Over-LAN (SOL) drivers, as well as Intel Management and Security Status (IMSS), to support Intel Active Management Technology (AM.

The 790/990 'serial port drivers' are not 'COM port drivers' that are built into the OS all the way back to MSDOS. They are INTEL AMT SOL (Serial over LAN) drivers. These drivers are not built into windows. Since the 790/990 also has WDDM 1.0 VISTA drivers then they work from DOS to windows 7.
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.
