With the rise of tablets, e-readers and smart phones, along with ever-increasing screen quality people are doing more with digital screens than ever before. This is especially true for ‘screenagers’, the younger generation of millennials who have grown up in a screen-based culture of social media and mobile devices.

However, even in our increasingly digital-reliant society, paper still plays a major part in how we work. According to a 2017 survey of over 200 office South African workers commissioned by Epson Europe, 73% of employees use printers more than once a day and those who do, print 20 items on average, which equates to around 36 pages each day.

Does this reliance on paper in the workplace mean a need for a break from staring at screens, or is there a more scientific explanation behind paper’s longevity, and is it possible to process information on paper differently than we do on screen?

When it comes to ‘skimming’ over content or giving something a quick read, on-screen reading works better for some than others. However, people still turn to paper for thoughtful and careful reading, whether it’s in schools or in an office environment.

In the workplace, the most popular printed items include invoices and letters, which employees say make up 48% and 46% respectively of all items they print in a typical day. These items are typically text heavy and are often the source of critical background or legal information, requiring a comprehensive understanding of the text, which would explain their prevalence in the office. Invoices and letters are also more likely to be edited and treated with extra attention than other items.

Research shows that the number of business emails sent and received per user, per day, reached an estimated 123 emails during 2016. This figure is expected to grow to an average 126 messages sent and received per business user, per day, by the end of 2019. With these figures and predictions in mind, it is easy to see why email attachments account for 45% of all printed items, and 39% of these making up the total number of items printed.

Employees have also highlighted their biggest reasons for printing instead of screen-reading, with 40% of respondents saying that they need hard copies of legal documentation and contracts. A further 38% of people print items out for the purposes of archiving or keeping items on file for future reference, while 36% prefer to print out proof of purchase from their banks and concert tickets, presumably because having hard copies provides peace of mind.

Scientific research, although in its early stages, creates a foundation for the ongoing argument of why paper will always have its place in most institutions, demonstrating that reading from print results in much higher levels of comprehension, learning, information retention and ease of use. This can be partially explained by the reader’s ability to move through text in a non-linear fashion – the opposite of reading from a screen – and being able to flick through pages with ease.

Screen technology is currently unable to replicate this tactile experience, even with the advent of flip books on reading devices or flip page magazine PDFs online. Some scientists even argue that simply feeling the paper between our fingers also supports comprehension of text – known in a 2011 study by Gerlach and Buxmann as “haptic dissonance”, referring quite literally to “grasping something”.

Furthermore, several other academic studies (Wastlund, Reinikka, Norlander and Archer) reveal that the brain is under much more stress when reading from a screen, becoming tired more rapidly, compared to reading from paper. Studies have shown that the brain can function for a much longer period when reading from paper, with screens draining more of the brain’s resources during the reading experience, making the comprehension of information more difficult.

In addition, reading on interactive devices requires more discipline as it allows for multiple distractions. For instance, an email may appear while proofreading or we may be tempted to leave the document to browse the internet or social media. When working on paper, there is less opportunity for distraction and readers are less likely to multi-task.

In order to be productive, we must determine what works for us as individuals, and in which instances working on-screen or off-screen is the best choice. However, in the words of futurist Jack Uldrich, “every technology has unique and tangible benefits, and paper is no different. Arguably, paper is the greatest instrument ever invented for conveying, sharing and disseminating information.”
