Bug#433499: does not scan anymore
let's keep the bug report in the loop, that was my fault... also sprach Jeffrey Ratcliffe [EMAIL PROTECTED] [2007.07.18.0937 +0200]: Now I have an HPOfficeJet, also running under HPLIP with an ADF, and gscan2pdf works fine. I also don't understand why you would need the -b (or --batch) option and the redirect, as the point of the --batch option is to produce one file per page. I don't have a scanner on this machine to test it. Do you still get out%d.pnm, or are all pages somehow concatenated in output.pnm? I should be more specific: ADF works. It does not seem to work if I use the flatbed. Anyway, despite the error, using batch-scan=no or not using batch-scan does actually produce out1.pnm, which it should.

Bug#433499: does not scan anymore
Does it work if you set batch-scan=no and scan from the flatbed? Yes, then it works, sort of: piper:~ scanimage --device-name='net:sane:hpaio:/net/HP_LaserJet_3052?ip=192.168.14.31' --mode='Grayscale' --contrast='50' -x 210 -y 297 -l 0 --compression='JPEG' --resolution='200' -t 0 --source=Auto --batch --batch-scan=no | /tmp/scan.pnm Scanning -1 pages, incrementing by 1, numbering from 1 Scanning page 1 Scanned page 1. (scanner status = 5) Scanning page 2 scanimage: sane_start: Error during device I/O It occurs to me that here, you should be specifying that you only want 1 scan: scanimage --device-name='net:sane:hpaio:/net/HP_LaserJet_3052?ip=192.168.14.31' --mode='Grayscale' --contrast='50' -x 210 -y 297 -l 0 --compression='JPEG' --resolution='200' -t 0 --source=Auto --batch --batch-scan=no --batch-count=1 Assuming this works, perhaps I should add a check to gscan2pdf that forces number of pages to scan to be 1 if batch-scan=no. Anyway, despite the error, using batch-scan=no or not using batch-scan does actually produce out1.pnm, which it should. I was just put off by the error message. I'd rather not suppress the error message, because the same message can be produced by a real problem. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

If the ADF is not in use, that's the same as 1. I don't see why I should have to specify this explicitly. For --source, you only have options Auto or ADF, so the only way to know whether the ADF is in use is to assume it isn't if --batch-scan=no. Some scanners don't have a --source option if there is only one possibility, or have wildly varying names for ADF, flatbed, etc. Only HP uses the --batch-scan option. Unfortunately, this isn't straightforward. If I scan with batch-scan=no and all batch-count=all, then it works but simply takes ages processing page two before closing the dialog. So if I understand you correctly, you *can* make it work. It just isn't as intuitive or quick as you would like.

the --batch* options passed to scanimage. See below.

Usage: scanimage [OPTION]...
Start image acquisition on a scanner device and write PNM image data to
standard output.
Parameters are separated by a blank from single-character options (e.g.
-d epson) and by a = from multi-character options (e.g. --device-name=epson).
-d, --device-name=DEVICE use a given scanner device (e.g. hp:/dev/scanner)
--format=pnm|tiff file format of output file
-i, --icc-profile=PROFILE include this ICC profile into TIFF file
-L, --list-devices show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of the output
can be specified: %d (device name), %v (vendor),
%m (model), %t (type), and %i (index number)
-b, --batch[=FORMAT] working in batch mode, FORMAT is `out%d.pnm' or
`out%d.tif' by default depending on --format
--batch-start=#page number to start naming files with
--batch-count=#how many pages to scan in batch mode
--batch-increment=#increase number in filename by an amount of #
--batch-double increment page number by two for 2sided originals
being scanned in a single sided scanner
--batch-prompt ask for pressing a key before scanning a page
--accept-md5-only only accept authorization requests using md5
-p, --progress print progress messages
-n, --dont-scanonly set options, don't actually scan
-T, --test test backend thoroughly
-h, --help display this help message and exit
-v, --verbose give even more status messages
-B, --buffer-size change default input buffersize
-V, --version print version information
Options specific to device
`net:sane:hpaio:/net/HP_LaserJet_3052?ip=192.168.14.31':
Scan mode:
--mode Lineart|Grayscale|Color [Grayscale]
Selects the scan mode (e.g., lineart, monochrome, or color).
--resolution 75|100|150|200|300|600|1200dpi [75]
Sets the resolution of the scanned image.
Advanced:
--contrast 0..100 [50]
Controls the contrast of the acquired image.
--compression None|JPEG [JPEG]
Selects the scanner compression method for faster scans, possibly at
the expense of image quality.
--jpeg-compression-factor 0..100 [10]
Sets the scanner JPEG compression factor. Larger numbers mean better
compression, and smaller numbers mean better image quality.
--batch-scan[=(yes|no)] [no]
Guarantees that a no documents condition will be returned after the
last scanned page, to prevent endless flatbed scans after a batch scan.
For some models, option changes in the middle of a batch scan don't
take effect until after the last page.
--source Auto|ADF [Auto]
Selects
