How I can get this HP Smart tank 7000 printer to print (in colour) on my MacBook Pro?

This HP printer supports AirPrint, which means macOS, iOS, and iPadOS can and will use the printer drivers embedded directly within the printer. Nothing additional or added is needed. Printers with AirPrint are what you want to buy, as these printers don’t need added drivers.

Here is how to configure an AirPrint printer on macOS:

There’s a firmware update from last year for this HP printer. Make sure that’s installed:

HP would prefer you to load the HP Smart app (that’s the HP driver package), though that’s not necessary here as this printer supports AirPrint. HP Smart also includes lots of background activity doing who-knows-what, based on various system reports that get posted around here.

Here’s the full HP manual for that HP Smart Tank printer, including a brief reference to AirPrint, for reference:

Amusingly here, HP co-invented AirPrint with Apple, but it seems HP Support is unaware of that and of related details.

For others reading here in the future, and considering which printer to acquire:

Local preference is Brother. The last HP printer was wheeled out of here a few years back.

With the same thing happening on both printers, I would look for a software conflict in your system files. The best way to do this is to provide the free EtreCheck report by using the Additional Text option when posting. This will will show the files that are installing on startup without any personal information and we may be able to identify files that should not be running.

When I first installed my HP printer using the HP Smart App it did not print in color. The Smart App was needed to connect the printer to the same Wifi network as my computer, but also installed the HP driver. After going to Printer settings and removing that driver, I added the Bonjour/AirPrint driver and have had no trouble since.

From the HP site:

NOTE:

• Disconnect from Virtual Private Network (VPN) connection before downloading.
• If you are asked to sign in to a Microsoft Store account, you can either sign in, create one or close the sign in screen and continue to install HP Smart.
• HP Smart is compatible with Windows 11 and Windows 10 version 1809 or higher. HP values that updated operating systems offer our users increased security and privacy protection.

I think you'll need Windows to use this printer. That's what HP certainly seems to be saying.

Thank you to everyone who has replied. I have been using AirPrint but it only prints in black & white anything with colour comes out in B&W.

Have you updated the printer firmware? if not, start there.

If it is offered on your printer, ensure that Print in Color is selected:

I've MacBook Pro M1 2021 with the latest Sonoma 14.3. I also have two printers Epson XP-8700 and HP Smart Tank 7000 with the latest firmware and SW (installed like 7 times). I bought the HP because my Epson continuously lost the connection to my MacBook Pro M1 and failed to print or scan until Mac was rebooted or the printer restarted (off/of). Having bought the HP I have the same issue. It prints and scans fine for a day or max two until it loses connection to Mac (error code: failed to open a connection to the device (-21345) - same with the Epson). Switching off the HP or rebooting the Mac are the only ways to get both, the printing and scanning back (for a day or two). AirPrint on HP IP address works (also in colour) but no scan. I can connect to the HP printer through the HP Smart App but only to print (also the app sort of sucks ... for a lack of better description ...). I've been in touch with the Epson and HP support and Apple support the last, but in vain. No-one in any of these offices have a clue what's going on. I'm only happy they're not designing SW for airplanes ...

I'll keep on switching the HP off/on every other day when I need to print or scan and wait for the day when AI comes in to my rescue.

That's a quite from the site; right there for all to read.

You should be able to use the printer if you set it up to use wireless or Air print. Take a look here
