User questions & answers

Question:	Will this work with the newer chromebooks and Android
Answer:	Yes, it has a USB-c port on the printer. Also, comes with USB to USB-c cord.
Question:	Will it print using a cord to phone or tablet without internet connection? I’m in the middle of nowhere often without a signal
Answer:	Yes, the printer comes with a usb to usb-c cord. If your phone/tablet doesn't take usb-c you would have to get a different cord to do so. You can also set the printer up with a direct connection instead of over wi-fi.
Question:	Does this come with everything needed to set up and use
Answer:	Yes. It comes with the printer, both ink cartridges, and all instructions including CD for windows installation. for phone/iPhone/mac the instructions have a qr code to scan to set up, Also has an added bonus of a USB to USB-c cord.
Question:	can i use only black cartridge only? i don't print in color
Answer:	the printer wont work if you don't have both cartridges properly installed. That being said, just because it has to have a color cartridge doesn't mean you have to print in color. It comes with both cartridges. Just install the ones that come with the printer. If you never print in color, then you will only have to replace the black ink cartridge. Also, you can get ink for this printer for way less than the cost of other printers cartridges. That sold it for me. The printer has worked great, and the compact design is perfect for a small space. It fits on my small utility cart with room to spare!

User questions & answers

Question:	Does it print both sides of paper
Answer:	No it doesn't. You can manually make it by flipping the page, and replacing it in the feeder tray.
Question:	Can you print on card stock with this printer
Answer:	I was printing on 65 pound card-stock and my printer accidentally sucked two pieces through the printer and printed just fine. So I imagine it would handle 110 pound card stock just fine.
Question:	Does this come with ink
Answer:	The cartridges that come with the printer are standard, full size, cartridges. You can purchase XL cartridges as replacements which will save you about 20 percent per page. There is also the option to subscribe to an Automatic Ink program called instant ink. You pay $3.00 a month and print up to 50 pages. If you print more, HP will charge you an additional $1 for each eset of 15 pages or more that you print. Most importantly, when you run low on ink, HP sends you more ink long before you run out. Best of all, you get fresh ink while only paying your $3 a month. At ~$0.06 a page, it's the lowest cost way to print, as long as you print every month. And, if you print photos, Instant Ink subscription is an absolute bargain saving you 85% on ink.
Question:	Does this come with a wire if you don't want to use wireless
Answer:	Cellular costs, WIFI should be free. You're being ripped off. WIFI is the same as a wireless home phone. You don't pay the phone company for a wireless home phone, you pay for the phone service. WIFI is the same, if you have a WIFI router, you have WIFI, if not, you're wired. The internet service is the same. Cellular internet service on the other hand, costs.

User questions & answers

Question:	Does it print from dell computers or just Apples
Answer:	I have a Dell and it prints great
Question:	Can I get the perspective of a photographer on this question: How well are colors reproduced compared to the original? Does the software auto touchup
Answer:	I'm sure its okay... It's Epson been a graphic designer for 10+ years. Epson is always my go to brand for proof printers. But the cartriges are RGB (I think) and black so color range is limited vs the 8+ color models and wouldn't print very many full color prints. I'm not around the printer now but cartridges were foam filled instead of liquid ink, and about 2.5x2x1. Nothing but a gut feeling one or two saturated 8x10's you'll be out of at least one color or more.
Question:	What is the actual size (folded up for transport) and weight (the description lists 4.6 lbs AND 3.5 lbs
Answer:	3.5 lbs with ink installed. Been using for 2 weeks, and GREAT for printing up on the fly docs. Direct print from iDevices works well, have to use mini-USB for MacBook.
Question:	can you use USB cord to connect directly from laptop to printer without setting up wireless connection
Answer:	Can you connect and print from an IPAD 7 with a USB to lighting cable?
