This replaces an 11 year old HP all-in-one and for the most part it is a much better printer. Upgraded from 8x10 to 11x17 size max scan size. Because of the larger scan size and 2 trays this is a beast bigger and heavier than older machine. PROS 1. 2 paper trays & auto select picks letter or legal correctly when size is specified 2. Scans duplex without re-feeding paper through the machine- 1 pass gets both sides. 3. Duplex scans legal size documents (old printer couldn't) 4. Scan and print quality very good 5. Prints faster than old machine w/text only very fast. 6. Setup was fast and easy all computers in household recognized and set up drivers very fast. 7. Paper trays will accommodate up to 11x17" paper 8. Software for scanning provides more flexibility in selecting scan options than old software and works really well. 9. Used several types and sizes of paper and so far no jams feeds everything well. CONS 1. Size of the display it is tiny about half the size of the old printer. Makes it very hard to see what is on the screen and with big fingers like I have getting the right item pressed especially on the top of the display is almost impossible. Using a stylus for this thankfully don't use display often. 2. Document handler only holds 35 sheets old one held 50. 3. Tray where scanned documents goes after being scanned is WAY TO SHORT. HP reduced the height of this to save space since the unit is so big. so it is just under 1" and the papers don't stick out very far from the document feeder above. This makes it difficult to pull the papers out after they are scanned. 4. Software for scanning and printing are buried in a master program. Must start main program which takes a while to load, then select for scan wait for that to load then select scan from there so 3 mouse clicks to get to scan a document. Old software allowed that program to be started directly from desktop icon. Way faster. Haven't been able to find a way to do that with this software. 5. Smart chip in ink cartridges and HP constantly auto updating firmware to make use of 3rd party cartridges very difficult. Checking several ink suppliers looks like you can work around that a bit. I know ink is where the profit is but still ink is waaaay to expensive.
