The actual printing technology is handled by two cartridges that load into the center of the Officejet 100: one tricolor and one black. Using the calculations and page yields for the standard-size cartridges listed on the site, a full page of black-only ink will cost 5.5 cents per page, while a full-color print will run you 8.8 cents per page. Along with the high premium you'll pay for the initial hardware purchase, you'll also shell out more cash than average to refill it. At least HP cuts you a deal with its extra-large ink cartridges that cost slightly more but save more in the long run.
The Officejet 100 continues to demonstrate the impressive print speeds of HP's mobile line, with results that compare favorably with the older versions. It printed 5.9 pages of text per minute, 1.9 presentation slideshow pages per minute, and just under two full graphic sheets a minute as well for slightly faster metrics over the H470, and we're also impressed that the printer requires little to no warmup when you power it on; we imagine this asset will prove useful for print jobs where time is a factor.
The Officejet 100 is also deserving of praise for qualitative output improvements compared to the H570. Where we expressed disappointment with its predecessor's inability to produce clean character formations and jagged-free edges, this iteration exhibits near laserlike qualities in text, and graphic pages that expose accurate coloration and seamless shading transitions. Our only issue is that the snapshot photo prints we produced using HP's own photo paper lack the vibrancy that we're used to seeing in HP's desktop printers, but we wouldn't recommend this printer as a go-to accessory for hard-core digital SLR photographers anyway.
