Update:
I have done some more test. The issue occurs also with resolution 600 (not only
1200 as stated earlier). The issue is related to resolution/width/height
scanimage --mode color --format jpeg --resolution 600
-x 128 -y 87 -> Application transferred too few lines
-x 128 -y 88 -> OK
-x 129 -y 88 -> OK
-x 129 -y 89 -> OK
-x 130 -y 89 -> OK
-x 130 -y 90 -> Application transferred too few lines
scanimage --mode color --format jpeg --resolution 1200
-x 128 -y 87 -> Application transferred too few lines
-x 128 -y 88 -> Application transferred too few lines
-x 129 -y 88 -> Application transferred too few lines
-x 129 -y 89 -> OK
-x 130 -y 89 -> OK
-x 130 -y 90 -> Application transferred too few lines

Title:
Scanning issue with Ubuntu 18.04 and HPLIP version 3.21.2
Status in hplip package in Ubuntu:
New
Bug description:
Hello HPLIP team,
Since some days I have an HP Smart Tank Plus 555 printer connected to
Ubuntu 18.04 with HPLIP installed. Everything works fine so far, but I
have an issue with scanning. The images are not scanned correctly with
highest resolution 1200 dpi (lower resolutions are working fine)
My system configuration is
Ubuntu 18.04 with most recent updates
HPLIP version 3.21.2, scan utility version 2.2
HP Smart Tank Plus 555 firmware version POSPPWPP1N001.2051B.00
The HP printer/scanner is connected via USB
I scan the image with:
scanimage --mode color --resolution 1200 --format jpeg -l 0 -t 0 -x 88 -y 129
> image.jpeg
scanimage terminates with the error message „Application transfered
too few scanlines“
The scanned image has indeed missing pixels at the end of the
file/image. The issue occures only with 1200 dpi, not with 600 dpi or
300 dpi. Since I hade no issue in the past with my former HP
printer/scanner or lower resolutions I believe this issue is very
likely related to HPLIP and/or the HP Smart Tank Plus 555 device.
Would be great if one of the developers could take care of this issue
and hopefully provide a bug fix.
Best regards,
Helmut
