This half size card provides an LPT parallel printer port. The LPT parallel printer port uses the standard 25 pin female 'D' connector.As PCI is fully Plug & Play compatible, the operating system or BIOS automatically configures the card ensuring conflict free installation.Low-Profile PCI is a new PCI card standard for space-constrained system designs. The new form factors maintain the same electricals, protocols, PC signals and software drivers as standard PCI v2.2 expansion cards. They are also mechanically similar; however, Low-Profile PCI defines a shorter card and new mounting bracket for card retention. The Low-Profile PCI definition is an engineering change notice to the conventional PCI specification, Revision 2.2.
