Hi, I finally got around to testing the new escl backend with my HP OfficeJet 6978. It does appear to be supported on two ports, one encrypted:
device `escl:https://10.1.40.2:443' is a ESCL HP-OfficeJet-6978 SSL flatbed scanner device `escl:http://10.1.40.2:8080' is a ESCL HP-OfficeJet-6978 flatbed scanner Preview and higher resolution scans are OK. However, there appears to be something squiffy about the geometry options. I cannot get a full sheet scan. This is what I get from scanimage as regards the available options: Options specific to device `escl:https://10.1.40.2:443': Scan mode: --mode Gray|Color [Gray] Selects the scan mode (e.g., lineart, monochrome, or color). --resolution 75|100|200|300|600|1200dpi [75] Sets the resolution of the scanned image. --preview[=(yes|no)] [no] Request a preview-quality scan. --preview-in-gray[=(yes|no)] [no] Request that all previews are done in monochrome mode. On a three-pass scanner this cuts down the number of passes to one and on a one-pass scanner, it reduces the memory requirements and scan-time of the preview. Geometry: -l 0..0.0122375pel (in steps of 1.52588e-05) [0.000244141] Top-left x position of scan area. -t 0..0.0156708pel (in steps of 1.52588e-05) [0.000534058] Top-left y position of scan area. -x 0..0.0119934pel (in steps of 1.52588e-05) [0.0386658] Width of scan-area. -y 0..0.0151367pel (in steps of 1.52588e-05) [0.0529785] Height of scan-area. Using the current PPA from Rolf as of today, which is probably gonna be *git commit 1942c5fd.* Cheers, Ralph
