Do you be seated next to an office laser beam printer that’s in heavy use? Perhaps you have ever before wondered whether it could be doing you harm?

Well, this field is still in its infancy, but researchers have demonstrated that laser printing creates a shower of tiny particles, which stay in the air and may be inhaled deep into our lungs.

Whether these particles are harmful is the subject of ongoing exploration - however, generally there is evidence that similar-sized particles from different sources may destruction our hearts and lungs.

A global expert in this area, Professor Lidia Morawska, of the International Laboratory for QUALITY OF AIR and Health at Queensland University of Technology, started the ball rolling with a 2007 study demonstrating office laser printers emitted significant degrees of ultrafine particles.

No, she wouldn’t sit up coming to a busy office laser printer.

“We found that a number of the printers inside our office were weighty emitters so we evacuated them in to the corridor, where there is very good ventilation,” she says.

Tiny particles

As the name implies ultrafine particles, are very tiny - significantly less than 0.1 micrometres in diameter. To photo that, mentally divide a millimetre into 10,000 parts, and that provides you a concept of the size.

Other resources of ultrafine particles include vehicle exhausts, burning wood and candles, and cooking.

Since their initial study in 2007, Morawska and her team have discovered more about how laser beam printers emit these contaminants.

When the printer toner and paper pass above the hot printer roller, chemicals - known as volatile organic and natural compounds - are released into the air.

“These substances then react with ozone found in the weather and condense to create ultrafine particles”, says Morawska.

“The temperature of the printer is the key thing,” she explains.

“The hotter the temperature the more contaminants are produced.”

Their investigations also have shown:

– There is tremendous variability around printers with most creating 1000 times more particles than others.
– Different models created by the same supplier can produce completely different levels of particles.
– Two machines of the same model type may also differ within their emissions - if you have recently done much more printing, it’s more likely to create more particles.
Should we worry?
– A Federal Government-commissioned research looking at ultrafine particles from combustion and car or truck exhausts found data that high degrees of these particles can bring on asthma attacks in persons with the condition and worsen heart disease.

However, the large-scale research that are really had a need to answer these problems about safety have certainly not been done. Due to this, the World Health Organisation has not issued any rules on safe degrees of ultrafine particles.

Also, the ultrafine particles from laser printers happen to be chemically not the same as the ones investigated in the federal government study, so they might not exactly possess the same results on our bodies.

Safe Do the job Australia has commissioned two projects to especially examine potential health threats from laser beam printer emissions. The reports are expected to be available on the organisation’s website in arriving months.

So with no clear guidance how to handle this probable risk from laser beam printers, what - if anything - should we be doing?

Well, Morawska suggests erring on the side of caution, and provides these tips to minimise exposure to the ultrafine particles connected with laser printers:

– Make sure any office is well-ventilated with oxygen from outside
– If possible, locate heavily-utilized printers in well-ventilated areas, from people
– Avoid position over the printer since it prints
– In case you are sitting up coming to a heavily-utilized printer, consider requesting you or the printer to move
– People who have asthma or heart disease would be best advised never to sit near busy printers

Morawska has compiled a good set of printers her team has tested. While not exhaustive, the workforce has tested many designs, and occasionally tested different printers of the same model. You will find this list on her behalf website.

Just about everyone has been there - decisions, decisions. Choosing the right kind of printer, either for home or work, has never been a walk in the recreation area. One tricky component of shopping for a printer is without a doubt deciding whether to acquire a laser beam printer or an inkjet printer. And for good reason.

Both types of printers employ different approaches, with each suitable for distinct printing needs. As you may anticipate, each printing technology provides its pros and cons. However when it comes to buying a printer, the price -both first and ongoing - is definitely paramount. Which begs the concern: which is cost-successful, an inkjet printer or a laser printer?

This blog page post looks to offer you a succinct direct on the pricing of both laser and inkjet printers. It’ll look at the initial selling price tag as well as the expense in the long haul. Read on; you can be glad you did.

But first, let’s explore a few rudiments.

What exactly are Inkjet and Laser Printing?

Back in 1969, a good luminary Xerox employee named Gary Starkweather had a nifty little proven fact that marked the birth of laser printing. Simply put, Laser printers render a digital photo by scanning a laser beam across photoreceptors. Essentially, a laser beam printer utilizes a toner cartridge and a thermal fuse. On its component, inkjet printers perform the same by spraying liquid ink through a raft of minute nozzles onto the paper.

Price Tag

I’ll admit from the outset that you can garner a simple inkjet or laser beam printer for virtually the same price. Quite unexpected, right? When you are looking for a standard printer that can print as well scan and photocopy, there is simply very little difference in pricing. There’s little if any difference in the costs of a spending plan all-in-one printer like Dell 1133 and Canon MX350.

What’s the most obvious difference? A budget laser beam printer is only with the capacity of churning out dark-colored and white prints. Conversely, an inkjet release can print color docs.

If you crunch quantities, a laser beam printer is a little more expensive. You can garner a simple laser printer for something similar to $130. An inkjet substitute will set you back around 65 bucks. You will find a get, though: they commonly come filled with a starter cartridge that is almost spent, implying that a refill is inevitable.

Ongoing Cost

With time, printers require consumables like toner, ink, and paper. You can estimate the running expense of a printer utilizing a normal cent per A4 site. A budget laser beam printer capable of making only black and bright white documents has an average cost per site of around 6 cents/page. However the rate drops significantly in the event that you go for a higher price tag.

An inkjet printer typically rakes around 20 cents/site for both color and black & white prints. For dark and white pages, the price drops to around 7 or 8 cents/site. What’s more, laser beam printers have extra repair costs if pit against inkjet printers. You will need regular replacement of pieces like fuser cartridge.

Parting Shot

Pound for pound, inkjet printers are actually more economical than laser printers for low-switch printing. If you happen to do large printing, you’ll be better of with a laser beam printer.
