Security and USB Ports on Lexmark Devices

CaptureAbstract

Virtually every personal computer sold today contains Universal Serial Bus, or USB, ports by which a wide array of devices can be attached. As with most technologies, the nature of USB support involves a measure of security exposure, since most anything that can be used can also be abused — theoretically if not practically.

Many Lexmark laser printers and multifunction printers (MFP) include support for USB devices, and it is appropriate to consider the potential security ramifications of that support. This white paper describes the security considerations related to USB ports on Lexmark devices, and explains the protections that have been put in place to address those security concerns.

Executive Overview

USB ports on personal computers provide a means to connect devices of various types and perform a variety of interactions. However, for security reasons the USB ports on Lexmark devices are far more limited in their capabilities.

The USB host ports on Lexmark’s devices provide the following:
• When a USB mass storage device (such as a thumb drive) is inserted, the printer finds and displays by name the image files and/or flash files that are stored on the device.
• The user can select jobs to print from the displayed jobs. If a flash file is selected, the printer firmware will be updated as long as firmware updates are allowed in the security settings.
• Additionally, a user can scan data directly to the USB thumbdrive if it is available in a supported scan format. continue reading...

Supercharge Booting Servers Directly from a Storage Area Network

CaptureIntroduction
Traditional servers today use a variety of data storage solutions, including direct attach (DAS), network attach (NAS) and storage area network (SAN). Historically, these servers were configured to boot their operating system from an internal storage device (typically a parallel SCSI hard disk). As organizations implement large-scale data centers, sometimes with thousands of servers, they have sought methods to increase efficiencies through exclusive use of shared storage even for booting. In addition, with the dramatic increase in the use of rack-mount and blade servers, there is a particularly acute need to convert to diskless servers and rely completely on shared storage devices.

This paper discusses the capability of booting servers directly from OS images located on the SAN through a Fibre Channel host bus adapter (HBA) or a Fibre Channel over Ethernet (FCoE) converged network adapter (CNA). It describes the Emulex “Boot from SAN” implementation, and how it delivers a markedly enhanced level of manageability and availability, even in heterogeneous computing environments with distinct hardware and operating system requirements. Finally, it describes the four major steps involved in properly configuring a server to “Boot from SAN.”

What is “Boot from SAN”?
“Boot from SAN” has become a de facto description for the capability of servers loading and executing an operating system from a device on the SAN. A SAN provides a common link between multiple servers and storage systems, allowing independent scaling of storage and/or server processing power as requirements demand (see Figure 1).

On the Open Road to CIM with JDF An EFI White Paper on Computer Integrated Manufacturing

CaptureIn today’s market, pricing pressures are intense and profit growth is hard to find. Printers, prepress services, in-house graphics departments, and others are seeking a clear path to streamline workflows, reduce costs, and enhance profitability—and EFI® believes that
Computer Integrated Manufacturing (CIM) is that path. The goal of this whitepaper is to explain how, by implementing CIM using the open JDF standard from CIP4, printers can turn these challenges facing the industry into real opportunities for success.

CIM is the application of computerization to seamlessly integrate the flow of production instructions throughout the print workflow—reducing wasted time, labor, and material—and to automate or eliminate inefficient steps. While CIM has been a cornerstone for many manufacturing industries since the late 1970s, until recently it has been difficult to implement CIM in print manufacturing. Printing is the ultimate form of custom manufacturing—no other industry retools its production line for every job ordered (e.g., changing paper, ink, plates, bindery configuration, layout, etc.) Despite the need for flexibility, and the wide range of input materials that print customers bring to the manufacturing process, there are indisputable trends facing printers today that make the adoption of CIM concepts imperative. These trends include:

• Shorter runs, greater job complexity, and customers demanding shorter turnaround times make it necessary to optimize equipment and staff utilization for maximum throughput and cycle time reduction.

• Relatively slow print market growth and increasing competitive price pressures are driving print service providers to offer new, diverse services in addition to finding new ways to cut costs and improve profitability.

• Print shops are continuing to add an increasing number of devices with embedded electronic controllers that allow them to be integrated with other devices;

• The wide adoption of CTP (Computer to Plate) printing, digital printing and digital proofing, as well as standard file formats, now makes it possible to apply CIM to print production workflow.

These trends can be considered challenges or they can be opportunities for those printing companies who embrace the
application of CIM technologies to improve their performance, profitability and customer relationships. continue reading...

Bridging the Digital Divide Essential Strategies for Printing Success

CaptureIntroduction
There is no question that we live in times of dramatic change, and the Graphic Arts industry has faced its share of this change. In many ways, our industry has changed forever. For those who understand the implications of these changes and respond proactively, the future is bright.

Underlying success for any graphic arts service provider is the need to work within the context of an efficient, digital workflow, a workflow that must extend from the customer through final product delivery, invoice and payment, and which must span multiple technologies provided by multiple vendors.

This white paper will discuss the trends that are impacting graphic arts businesses and the changing needs of buyers of print and related services. And it will paint a picture of the successful graphic arts service provider, the technologies being deployed, and what these companies are doing to meet today’s challenges while preparing for tomorrow.

An Analog World No More
Much of the market shift the graphic arts industry is experiencing is due to a rapid migration to digital. Conventional analog production processes—from proofing to platemaking, from prepress to finishing—are rapidly being replaced by digital solutions. Film is giving way to computer-to-plate solutions. Offset presses are becoming more automated and in many cases, volumes are migrating from offset presses to digital printing devices.

While these changes have presented challenges, they have also presented significant opportunities. Many savvy graphic arts service providers have been quick to take advantage of these opportunities—and reap the rewards. By incorporating digital workflows and digital equipment into their operations, they have achieved new levels of efficiency and productivity, and they have been able to offer new services—and new levels of service—to their customers. continue reading...
