Test Conditions
Output Image: ISO JIS SCID No.5

Print Quality: Standard 600dpi
Print Size: A0 Size (827mm x 1,033.8mm)
Test Results:
Total Ink Consumed: 3.827ml

Cost Per Square Foot Calculation:
Based on the the above data, ink cost per A0 size (827mm x 1,033mm) printing is as below:

There are 2 print heads in a Canon iPF8100, hence the printhead cost per A0 size (827mm x 1,033mm) is as below:
2 units X MYR970 / 4,400 AO prints = MYR0.44 (USD0.13)
Ink Cost (per A0 print) + Print Head Cost (per A0 print)
= MYR4.10 + MYR0.44 = MYR4.54 (USD1.38)

1 ft = 304.8mm
827mm x 1,033mm = 2.71ft x 3.39ft = 9.19 sqft
MYR4.54/9.19sqft = MYR0.494 (USD0.15) per square foot
Hence, the Cost Per Square Foot for Canon iPF8100 is approximately MYR0.50 (USD0.15).
