I have this HP4515x monochrome printer in my office room and love its speed. This printer does what it is supposed to do without giving any trouble!!  According to HP, this printer prints each page in 8.5 seconds but I have never counted it!! I have printed some big .pdf files and never had any slowness or it never dragged. As with my experience with most of the HP printers, this is a no fuss printer. It can print both one-sided and double-sided. The double-side printing is automated and no need to painfully remove the paper and rearrange it.  It has 128 MB internal memory and has capacity to extend its memory!! The print quality is exceptional and installation is also easy if you follow the steps precisely. The only problem with all the HP printers is the cost of the cartridges. Though the printer can be easily purchased feeding it with cartridges is tough task. Though the expensive cartridges give us good quality print, our colleagues feel the cartridges are overpriced. So we also have an alternative printer for ordinary prints!!
