I'm very frustrated because I have several HP printers, and as they have become more internet-connected, they have become MUCH less reliable and likely to simply work. I would be delighted if someone would email or call me to help me.
This is my second buy in a bit over a year. The toner doesn't clog up like the less expensive ones and I'm no longer replacing it every couple of months.
It is so nice having a laser printer address 99.5% of my needs. Buying a large capacity refill unit after the original unit quickly died worked well. That one has lasted almost three years, so I am a fan of these extended use cartridge replacements.
