How much can I save on ink with the HP Instant Ink plan compared to standard inkjet supplies?

You can save up to 50% on ink with the HP Instant Ink Service plan. The comparison is based on the cost per page of the majority of color inkjet printers under $399 USD, with CPP comparisons for standard-capacity inkjet supplies based on estimated street price and page yield as reported by Gap Intelligence MFP Weekly and IJP Weekly Reports Q3 2013. Actual savings may vary depending on the number of pages printed per month and the content of those pages. (Page 2)
