Printing from iOS can not choose Color or Black and White

[aryobimo]

I saw a question with the same issue but the solution offered did not work

Fact:

- In the first few days after installation, iOS printing through HP smart works great, i.e able to Print by choosing color or B/W, quality (draft, normal etc.)

Problems:

- After less than a week, printing through HP Smart iOS does not show option of Color and B/W

- When printing, the picture preview shows B/W but the printing output is color

- Uses Draft quality but seems to use awful lot of ink (the paper feels soggy due to generous use of ink)

- Printing though iPad iOS even mark PDF as not supported though HP Smart Print app. Printing through Adobe works but still no option of color or B/W

- Printing through windows is not a problem choosing B/W or Draft quality

- Same issues with all 3 iOS device (iPhone X, iPhone XS, Ipad Air 3). Issue in iPad Air 3 worse as it says PDF printing is not supported. File in in apple Files App. All Devices with latest OS (13.3)

- Tried to update Printer Firmware. It says already the most updated

- Printer is connected to the internet

- All the remote printing setup up on on (i.e. Wifi Direct Print, AirPrint, EWS Print, Google Cloud Print)

Troubleshooting done:

- Tried to restore the Printer to Factory Default

- Tried to restore printer network setting to default

- Delete and Re-install HP Smart Print app in Apple iPhones & ipad

- Tried to restart all the devices with combination of above steps

- Tried all the setting in iOS HP smart app, Windows HP smart app, and Web app

- Tried pulling the plug of the printer

- Tried restarting the wifi router

None of the above attempt works.

Tap on the small grey bar above the printer name in the Print Preview screen.

That works initially when I first installed the printer. Like I said, in the beginning it works with the grey bar. Now when you tap on the grey bar there are no option for "Color" or "B/W". Like I also said, the preview is in B/W but the output is color
