22 Jan 20153D Printing and PWG Standards

What do two-legged dogs, a floppy airway, and a custom-built car have in common? The answer: 3D printing and PWG standards.

3D printing, considered a niche novelty a few years ago, is barreling into the mainstream. In recent months, a company called Local Motors debuted a mid-market prototype car using large-scale 3D printing, or additive manufacturing, creating building blocks much like Lego® bricks one layer at a time. And WinSun China is printing homes and apartment buildings!

3D printing is emerging as a solution not only for industrial goods, but also for medical applications. In two examples, South Carolina printing company teamed with a humane society to create artificial legs for a dog. Medical staff and engineers also recently developed biodegradable plastic splints and sewed them around a child’s bronchi to enable breathing. The 3D printing engineer/developer, who has previously focused on industrial parts, noted that this kind of printing capability “…(will) democratize manufacturing…”.

Importantly to the industry that develops printers and associated products and services, TechCrunch reports that the monetary investment in 3D printing “surged” in 2014. The site notes that “…Last year, spending on 3D printing and additive manufacturing hit $3.07 billion dollars, according to a report from industry analyst group Wohlers Associates. That number is projected to reach $12.8 billion by 2018, and $21 billion by 2020…”

So what does this mean for the IEEE-ISTO Printer Working Group (PWG) and its members, as well as to both enterprise and consumer users of these 3D printers? Much like the early days of the PC, networking, and storage industries that revolutionized our world, 3D printing is a bit of a “Wild West” when it comes to standards. Over the last 17 years the PWG has developed many standards for 2D printing, including the Internet Printing Protocol (IPP) and the PWG Semantic Model, which are widely adopted and have made network printing a predictable, reliable service.

By using similar approaches, 3D printers can streamline internal processing, ensure interoperability, and encourage development of standards-based applications and services. PWG standards also address security, not only for the confidentiality of print data but to provide access control and safe use.

The PWG is currently investigating how to best support networked 3D printers and invites all interested developers to participate in our discussions. The next 3D Printing BOF will take place on February 4, 2015 at the February 2015 face-to-face meeting. The PWG also has a 3D printing mailing list for discussing potential solutions and the necessary data models.

21 May 2013Printing from Mobile Devices, Part 3

The PWG has announced IPP Everywhere to enable printing from mobile devices without apps or vendor-specific drivers. In our previous post we talked about the advantages of allowing native printing capabilities. Users don’t have to download apps or update them. They don’t have to create accounts or sign in. Touch “print”, choose options, and you’re good to go.

But how will this work? IPP Everywhere is the brainchild of the PWG and its members, the heavyweights of printing. It uses Bonjour and ActiveDirectory to integrate into both home and office environments. It lets users print any kind of document securely.

IPP Everywhere builds on the well-understood and widely deployed IPP Standard. A number of other standards are incorporated: IPP Everywhere uses the JPEG file format for image printing and the PWG Raster Format or PDF for document printing. Bonjour and WS-Discovery are used for local discovery of printers and LDAP for enterprise printers.

How will IPP Everywhere be used? Users will be able to print from applications using standard UI, selecting IPP Everywhere printers that are available - this list of printers naturally will vary based on their current location - and then choosing options that the printer supports since IPP Everywhere knows what paper is loaded in a printer, whether the printer supports color, 2-sided printing, and other features.

As a result, users now can do all the work they could do on a PC at their desk with a smartphone or tablet - natively, easily, and without any special apps or vendor drivers.

Look for printers with these capabilities in late 2013. Most operating systems are likely to support them as well. More about IPP Everywhere is available on the IPP Everywhere Technology page.

17 May 2013Printing from Mobile Devices, Part 2

In a previous post, we talked about how printing from mobile devices has moved from a non-starter to a somewhat more complex capability based around vendor-specific apps and with little standardization. Wondering if mobile device users really do want to print something? In February 2013, IDC reported that:

“…according to a new International Data Corporation (IDC) survey of 800 unique respondents, smartphone and tablet users – whom the survey found to be younger, more likely male, have higher incomes, and increasingly hectic travel schedules – are surprisingly more likely than non-users to drive print. Smartphone and tablet users are more likely than non-users to print 16 of 20 business applications from their PCs.”

Further, the IDC report found that:

“…(the) percentage of users who printed from their mobile devices increased dramatically in 2012, and the percentage of those who do not print, and do not want to print, will decline from almost 50% in 2012 to just 25% in 2015 according to respondents. However, a large percentage of smartphone and tablet users do not know how to print from their devices, and a large share say their company has not yet enabled mobile printing.”

So what now? The Printer Working Group (PWG) has come up with a way to standardize simple printing without device-specific drivers or apps.

The Background

Some years ago, the PWG standardized the Internet Printing Protocol (IPP). In a nutshell, “IPP is a collection of open standards that define a high-level network printing protocol. IPP allows computers and mobile devices to query printer capabilities, monitor printer status and other state changes, do printer configuration, and submit, monitor, and control print jobs.”

IPP also supports encryption and authentication, streaming and compression, and managed print features ranging from paid printing to color management to duplex printing, stapling and others.

With IPP now supported in pretty much all printers, multi-function devices and enterprise copier systems, it made sense to build on it to enable printing from mobile devices. However, as we know, mobile devices present some pretty interesting challenges when it comes to printing…

First, mobile devices roam from network constantly. Second, the small, lower-cost form factor, including memory size, does not allow for the inclusion of device-specific drivers.

The PWG then looked at how to extend IPP to support these mobile devices. The result is IPP Everywhere, released early in 2013 and announced this week. IPP Everywhere lets users on mobile devices easily select a printer, choose output options, and print securely. No apps, no drivers! Unlike many apps or vendor-specific print tools, IPP Everywhere exposes the full range of printer capabilities such as borderless photo printing, 2-sided printing, stapling, and binding.

How will it work and when? Stay tuned…

NEW IPP EVERYWHERE STANDARD LETS USERS PRINT FROM SMARTPHONES AND TABLETS WITHOUT APPS OR VENDOR-SPECIFIC DEVICE DRIVERS

CUPERTINO, Calif., May 14, 2013 – Users of today’s smartphones and tablets can do almost anything on these devices – except print from them natively, without downloading apps or vendor-specific device drivers. Now, an industry standards group, the IEEE-ISTO Printer Working Group, has solved that problem with a new specification, IPP Everywhere.

IPP refers to the group’s Internet Printing Protocol that enables printing without drivers provided by vendors of printers or multifunction devices. The IPP standard is supported by all major printer manufacturers and in most operating systems. The new standard, IPP Everywhere, defines a new baseline for printing without vendor-specific driver software and includes support for mobile devices that constantly roam from network to network.

With IPP Everywhere, users can find and select a printer, choose printer-specific output options, and print their photos, web pages, documents, forms, and tickets securely without installing vendor-specific or model-specific software or drivers.

Unlike existing, proprietary solutions, IPP Everywhere exposes the full range of printer capabilities, from borderless photo printing to stapling and other finishing features offered by many office printers.

IPP Everywhere printers integrate seamlessly in both home and office environments thanks to the use of Bonjour and ActiveDirectory. Included geo-location information will enable future commercial printing services using the same core software on a user’s computer or mobile device.

“IPP Everywhere empowers users to not only access data and transactions but to print critical documents, even when roaming and not connected to their home networks. From airline boarding passes to secure documents, users of IPP Everywhere-enabled applications can express their specific printing requirements without installation of cumbersome vendor drivers or third-party apps,” said Paul Tykodi, principal consultant of Tykodi Consulting Services LLC and co-chair of the IEEE-ISTO PWG IPP working group.

Printer makers, many of whom are members of the PWG, plan to support IPP Everywhere with products to enable printing without vendor-specific software. PWG will offer a self-certification program as well.

“IPP gave printer makers an easy way to provide standardized print services, and the addition of printing without vendor-specific driver software in IPP Everywhere for mobile devices expands that ease of use to all,” noted Ira McDonald, co-chair, IEEE-ISTO PWG IPP working group.

More information including the specification documents, FAQs and more are located at https://www.pwg.org/ipp/everywhere.html.

The PWG is a program of the IEEE Industry Standards and Technology Organization (ISTO). Members include printer makers, print server developers, operating system vendors, network operating system developers, network connectivity vendors and print management application providers.

12 May 2013Printing from Mobile Devices

According to a recent Forbes blog on the growing use of smartphones and tablets, “Shipments of smartphones and tablet PCs are both on the rise, with the first up 40 percent and the second nearly 100 percent this year, market research firm TrendForce forecasts.” What does that mean for printing? Does everyone with a smartphone or tablet want to give up the option to print something from the device?

In the early days of these handy, computer-in-your-hand devices, users basically did just that. They accepted the limitations of the device and emailed themselves links, bookmarked pages and did all sorts of strange things to remind themselves to print that important document, email or website page when they returned to a PC which could connect to a printer.

Eventually, printer makers got smart and created apps that supported their brand devices. An Epson app let users print to their Epson printer and the like. And even Google, of course, has gotten into the game with an ability to print using its cloud services.

So what’s the problem, then? Well, for one, we are making it difficult for users to do something they’ve taken for granted for decades now: click a print button and watch something magically emerge from a printer. We’re asking them to install all kinds of apps, which might or might not work well, and to keep updating them, signing in and in general presenting a number of hurdles to doing something that is actually pretty simple.

For printer and other print device makers (multi-function devices, copiers, enterprise printers), we’re requiring them to create and maintain apps, make their devices work with these apps and keep up with the treadmill of new operating systems, new capabilities and the like. And in between, we possibly are foregoing security.

Clearly what’s needed is some sort of simple interface that is standard. That’s where the IEEE-ISTO (International Standards and Technology Organization) Printer Working Group (PWG) comes in. The PWG has labored quietly for years to create cross-industry, open and free technical standards that enable seamless printing.

More later this week as we look at the work of PWG and how it helps users and printer makers.
