Summary: Some are saying it doesn't last long. However it depends on what you print. All toners are based on 5% coverage. So if you are print 1 page at 100% coverage that page equals 20 pages. for us we are printing contracts and emails on this printer. we get about 10,000 pages per cartridge before the lines start showing up (30% left) it depends on what you print.
Excerpt: I have owned an Hewlett Packard P3015 laser printer for six months; this is a great Home Office/Small Office laser printer. The printer is the main printer for my business. I print approximately 40,000 pages per year. The HP CE255XD cartridges provide extremely high quality printed pages.
Pros: Clean Replacement, Dries Quickly, Easy to Replace, Long Cartridge Life
Summary: I ordered this printer for small business and it said it would print 6500 pages. I gave me a message the other day to replace the cartridge. I was having a hard time believing I had used up all my ink already and printed out the report for the pages printed. I had a total of 2288 pages printed. This was the first cartridge I have used but it must have been half dried up. Very dissapointing considering how expensive the replacements are.
