Our company use HP printers and almost all of them cause me so many problems. Well over 50% of our support calls are printer related. I've just been trying to sort out a problem where a printer won't delete on a system, the printer showing is one which was replaced but not showing the new driver and duplexing will not work.
It's crap, HP printer drivers are absolutely terrible. We use a lot of their officejet all in ones. They are slow, unreliable and the drivers are even worse than the standard pritners.
Our recent HP printers have also included the 2015, a very quick printer but we've had to return every single one at least once because it will gradually die and need restarting 3-4 times a day.
3505, driver support is pants and would simply print out hundreds of pages of random characters, we actually used a 3800 series driver to fix this.
I also find that when I go to set up a shared printer on our server that it takes hours sometimes to make the default settings retain. I also find that more than half of the time printers will set to letter instead of A4. Why it does it on some computers i don't understand and you have to change every setting about 5-6 times in different places in the printer setup.
We have a single epson on site and it just sits there working away, no issues what so ever.
I hate HP
