A:AnswerThe main difference is that the base model in this series does not support two sided printing and the HP Officejet 6500A Plus Wireless All-In-One Printer does.
A:AnswerThis printer has auto automatic two-sided “printing”, but the Automatic Document Feeder is single sided. You cannot to two-sided scanning or copying as a result.
A:AnswerHP ink cartridges should not be refilled. Refilled ink cartridges can leak in the printer requiring service that will not be covered under warranty. In addition, the print quality will suffer with refilled ink cartridges because the nozzles become clogged with this additional use. Please note that HP does not manufacture or support refillable ink cartridges. I apologize for any inconvenience this may cause.
A:AnswerNo this printer has a single printer tray. Consider the HP - Officejet Pro Premium 8500A Wireless All-In-One Printer. You can view this product at the following link:
