hp LaserJet Pro MFP M28w long delay before scan

[Arunas]

Scanner has long delay time before each scan. It takes long time to get scanned image to Simple Scan or XSane. Printer works fine. The delay before scan takes 45s, 20s more to get image on the screen, 15s till Simple Scan allows to press button for next scan.

Hi Arunas,

We are working on performance improvement for the upcoming releases.

I am on Ubuntu 18.10 and Mint 19.1 and can confirm this problem!
I bought a HP LaserJet Pro MFP M28w yesterday. On Ubuntu 18.10 and Mint 19.1 with HPLIP 3.19.1 when I used hp-scan without any parameters it took 1:08 minutes to start the scan. The whole process took about 1:51 minutes.
When I called xsane it took 20 secs to finish scanning for devices and open the main windows, 1:20 to acquire the colored preview, and it took 1:21 to scan the image at 300 dpi and show it in the Viewer.
I will keep using my F4480 to scan things on Linux until that problem is fixed.

Hello guys, I'm under linux Mint 19.1 too ...
How did you get the M28W to scan, actually?

I get this error:
(same with simple-scan)

I may add that mine is on wi-fi. I didn't try via USB, because I won't be able to use it anyway, due to the printer position.
Incidentally, the android HP app works: I can send documents in wi-fi.

[brian_p (claremont102)]

@Samuele Rini (and anyone else).

> I may add that mine is on wi-fi.

On Mint 19.1 you are also using HPLIP 3.17.10. That, plus being on the network, triggers https://bugs.launchpad.net/hplip/+bug/1797501. Solutions are at https://bugs.launchpad.net/hplip/+bug/1817214.

However, it would appear from other reports that this is not sufficient to restore scanning ability with the HP LaserJet Pro MFP M28-M31. Something else is going on and there is some additional advice in Message #9 at https://bugs.launchpad.net/hplip/+bug/1821932. It would be useful to know whether this works. (After fixing bug 1797501, of course).

Consolidating multile reports about scan problems with LaserJet Pro MFP M28-M31 to bug #1811504 as it seems to be the most advanced and even has a workaround.
