Tech Tip: Check ACPI compatibility/Add a printer for UNIX clients in Win2K

Learn how to check ACPI compatibility and add a printer for UNIX clients.

Windows 2000 Professional: Check ACPI compatibility

The Advanced Configuration and Power Interface (ACPI) is the most recent power management mode available on PCs, and ACPI offers several advantages over its predecessor, Advanced Power Management (APM). Advantages of ACPI include tracking the status of USB and FireWire devices, support for Wake On LAN and Wake On Ring, better battery management, multiprocessor support, and more.

You can upgrade systems that don't currently support ACPI with a BIOS upgrade. After upgrading the BIOS, you must reinstall Windows 2000 to take advantage of ACPI--you can't just use Device Manager to add the ACPI hardware abstraction layer (HAL). However, you should be able to perform an upgrade installation to install the operating system over the existing installation and retain applications and other settings.

One way to determine if your system is ACPI-compliant is to check the Device Manager. Look in the System Devices branch for the Microsoft ACPI-Compliant System item.

You can also check the Power Options applet in Control Panel for ACPI compatibility. If the Power Options dialog box includes an APM tab, the system is not ACPI-compliant, or, at the very least, Windows didn't recognize it as such during setup.

Windows 2000 Server: Add a printer for UNIX clients

If your network includes systems that run UNIX or Linux, it's likely that you need to allow these clients to print to printers hosted by Windows 2000 Server. With these clients, an application can use the Line Printer Remote (LPR) service to send a document to a print spooler.

While Windows 2000 and Windows XP clients don't need the LPR service to print to a TCP/IP-based printer, UNIX and Linux clients do still need LPR. The first step in enabling these clients to print to a printer hosted by Windows 2000 Server is to add Print Services for UNIX, which is included with Windows 2000 Server.

You can add this service via the Add/Remove Programs applet in Control Panel. Click the Add/Remove Windows Components button, and select the Other Network File And Print Services group. Click Details, choose Print Services For UNIX, click OK, and click Next to follow through the rest of the wizard.

Next, verify that you've configured the service to start automatically. Open the Services console, locate the TCP/IP Print Server service, and configure it for automatic startup. Start the service if it hasn't already done so.

Next, configure the target printer for LPR. Open the properties for an existing printer in the Printers folder, or add a new printer. If you're adding a new printer, choose the Create A New Port option in the Add Printer wizard, and add the LPR port type. If you're modifying an existing printer, add the LPR port from the Ports tab of the printer's properties.

After you add the LPR service to the printer, UNIX and Linux hosts will be able to print to it across the network.
