then

mkfs.vfat –F 32 /dev/sda1

From the web management console, select

USB Printers

The CyberGuard SG appliance’s print server allows you to share attached USB printers

with your LAN.

After it has been configured, the CyberGuard unit and printer will show up

when you browse your Windows workgroup or domain.

Mac OSX, Linux and other UNIX-based or UNIX-like machines on the network can use

the

LPR

/

LPD

protocol for remote printing.

This section describes how to configure the CyberGuard SG565 to share a USB printer,

and how to set up remote printing on a Windows PC.

Warning

Many inexpensive printers will not work with the CyberGuard SG's Print Server, as their

drivers expect the printer to be attached directly to the PC you are printing from, or the

printer itself relies on utilizing the PC’s CPU for processing print jobs.

Due to these

technical limitations, we simply cannot support these types of printers.

It is therefore strongly recommended that you use a business grade printer with

the CyberGuard SG's print server.

Non-business grade printers may work, but we are

unable to provide support if they do not; see the

Troubleshooting

section at the end of

this chapter for suggestions.

Additionally, advanced features such as cartridge status reporting may not function

correctly.

Multifunction and all-in-one printers are not supported.

Set up the print server

Attach the USB printer to the CyberGuard SG appliance and ensure the appropriate

driver is loaded, as described in

Attach the USB device

towards the beginning of this

chapter.

Select

Print Server

from the

Networking

menu.

Under the

Printer Configuration

heading, locate the printer and click the

Edit

icon.

Check

.

Enter a short descriptive

for the printer.

This is the name that will be displayed

when browsing your Windows workgroup or domain, and the name of the queue for

LPR

/ LPD

connections.

Click

Apply

.

Set up the print spool

By default, the CyberGuard SG appliance spools incoming print jobs into RAM before

sending them to the printer.

This can be an issue if you have many services running on

the CyberGuard SG appliance (e.g. many VPN connections, Intrusion Detection, Web

Cache, etc.) and it is low on RAM, or you are intending to print large documents or

images.

When a Windows PC sends a document or image to the printer attached to the

CyberGuard SG appliance, it first converts it into a format that the printer can read.

The

resulting file that the CyberGuard SG appliance has to store in RAM can be many times

larger than the size of the original document or image.

Note

To avoid the CyberGuard SG running out of RAM and print jobs failing, we recommend

that you use a USB mass storage device to spool print jobs.

If you wish to spool to RAM or set up the spool later, proceed to

Set up Windows PCs for

remote printing

.

Otherwise, follow the steps under in

Enable the storage device

in the

USB Mass Storage

Devices

section earlier in this chapter to connect and enable your USB mass storage

device.

Figure 10-7

Once this is done, select the USB mass storage device or device partition on which to

store the print spool from the

Select spool

pull down menu under the

Print Spooling

heading.

Note

You may simultaneously use a USB mass storage device or device partition as a print

spool and a Network Attached Storage device.

However, the spool directory will be

visible (as

spool

) and there is a higher chance of the device filling up, causing print jobs

to fail.

For these reasons, we recommend dedicating a partition or device for use as the

print spool.

For information on partitioning a USB mass storage device, refer to the

USB Mass

Storage Devices

section earlier in this chapter.

Join a Windows workgroup

Follow the step under

Set up Windows PCs for remote printing

Repeat the following steps for each Windows PC to be enabled for remote printing.

These steps are for Windows XP, they will be similar for Windows 2000 and 95/98.
