collate

Create duplex PDFs with a simplex scanner.

Usage

Scanning

Collate uses the eSCL protocol to discover scanners on the local network.

Make an interactive scan:

collate scan [flags]

Optional flags:

• --device <device>: Select a scanner by its advertised name or device URL.
• --source <source>: Select an input source by ID or name, such as Platen, ADF Simplex, or adf.
• --paper <paper>: Set the paper format to a4, a5, or letter.
• --mode <mode>: Select an advertised color mode, such as BlackAndWhite1, Grayscale8, or RGB24.
• --resolution <dpi>: Set an advertised source-specific resolution in DPI, such as 300.
• --output <path>: Set the output PDF path. The .pdf extension is added when omitted.

For example, to preselect an DIN-A4, ADF scan with 300 DPI resolution and save to document.pdf:

collate scan --source adf --paper a4 --resolution 300 --output document.pdf

List available scanners without scanning:

collate scan --device-list

Merge existing PDFs

collate merge [flags] -f <front.pdf> -b <back.pdf> -o <output.pdf>

back.pdf is assumed to be in reverse order by default, producing front 1, back N, front 2, back N-1, .... Use --backorder=forward when back pages are in forward order:

collate merge -f front.pdf -b back.pdf -o output.pdf --backorder=forward
