Model type View more details.

MFP stands for multi-function printer, and standard refers to inkjet and laser (mono/colour) printers.

MFP
Printer type View more details.

Laser printers include mono and colour options.

Recommended View more details.

We recommend all printers with a CHOICE Expert rating of 70% or more, as long as the MFP or standard printer also delivers a performance score of 70% or more for print quality.

CHOICE Expert Rating View more details.

The CHOICE Expert Rating for standard and multifunction printers, the overall score that determines which models we recommend, is made up of performance (60%), ease of use (20%), brand reliability (10%), networking (5%) and ink wastage (5%). The performance assessment for standard printers is made up of print quality (80%) and print speed (20%), while the performance assessment for multifunction printers is made up of print quality (65%), print speed (15%), scanning performance (10%) and copying performance (10%).

Printing quality score View more details.

Inkjet and colour laser printing is assessed by a panel of experts looking at a typical black-and-white letter (25%), an 8x10-inch high quality photo (20%), a colour spreadsheet (25%), a colour document with a mixture of graphics and text (25%) and moisture resistance (5%). Black and white inkjet and laser printing looks at a typical black-and-white letter (31.25%), a colour spreadsheet (31.25%), a colour document with a mixture of graphics and text (31.25%) and moisture resistance (6.25%).

Printing speed score View more details.

Colour inkjet and laser printing speed is assessed by measuring the speed to print the same documents, made up of 25% for the photo, 25% for the colour document, and 25% each for the letter and the spreadsheet. Black-and-white inkjet or laser printing speed is assessed by splitting assessments into equal thirds, and measuring the speed to print a mixed graphics and text document (33.33%), a letter (33.33%) and a spreadsheet (33.33%).

Scanning score View more details.

Scanning and copying are assessed by scanning and copying a magazine page, an 8x10-inch colour photo and scanning a 3D object.

Copying score View more details.

Scanning and copying are assessed by scanning and copying a magazine page, an 8x10-inch colour photo and scanning a 3D object.

Ease of use score View more details.

Ease of use is assessed by a team of experts running each product through everyday scenarios that replicate typical use.

Networking score View more details.

We set up wired and wireless connections, assessing the steps required and the adequacy of the instructions.

Ink wastage score View more details.

We consider the impact of the 'maintenance cycle' in inkjet models, which consumes ink when print-heads are automatically cleaned. Less ink used equals reduced expense. We use our 'average use scenario' – 1000 mono prints, 250 colour document prints and 250 full-colour photo prints over the course of a year. This is not tested on continuous ink supply system (aka big ink) printers. The 5% contribution to each overall score is distributed evenly across the remaining parts of the test.

Power consumption score View more details.

Power consumption is a small factor in overall cost, so we don't add it to the total, but it's included in the reports.

Excess ink usage for cleaning (%) View more details.

Inkjet printers that are only used infrequently run a maintenance cycle to clean the print-heads before use. We calculate how much is used over a three-week period. The higher the figure, the worse the performance – 400 would mean that the printer uses four times as much ink to clean itself as it does to print. We can't accurately calculate how much ink tank type printers use for cleaning so they don't get a score in this test.

Time from power on to start printing (seconds) View more details.

The time it takes from powering on to starting printing the first page, measured in seconds.

Noise assessment
Shop Ethical rating View more details.

Shop Ethical rates the environmental and social impact of the company (not the product) using independent sources. This rating is not included in our total score. The rating ranks from A (highest) to F (lowest); N/A means there is no rating for that company.

C
Reliability score View more details.

A high score means the brand (not the model) is less likely to have faults over time, according to CHOICE members.

Satisfaction score View more details.

A high score means CHOICE members are satisfied with the brand (not the model).

Service score View more details.

A high score means CHOICE members were happy with the support they received from this brand when they had a problem with their printer.

Can auto print both sides View more details.

This setting will reduce your paper consumption, without the need to manually feed paper back into the printer. Some models do support printing both sides manually, which is noted in the specifications.

Yes
Eco setting View more details.

This setting uses less ink. It lowers print quality but allows you to limit full quality printing to important documents.

No
Availability View more details.

'Tested model' refers to printers that are currently available in shops and online, while 'Discontinued model' refers to printers that are no longer available in shops, but may be available second-hand.

Discontinued model

This is the recommended retail price, but you can usually find a more competitive price by shopping around.

Toner cost per text page View more details.

Annual ink/toner cost View more details.

This is the cost of one year worth of ink when you need to refill based on our average use scenario of 1000 mono prints, 250 colour prints and 250 full-colour photo prints over the course of a year. You may use more or less ink over the course of a year. Some printers include free ink in the box which can cover usage for up to three years. Prices listed in our table refer to refill costs after the free ink is exhausted.
