Greetings, list. I'm building a kiosk-based system that takes a scan, adds some text converts to postscript and then prints. The frontend calls scanadf to do the scan - problem is it runs too slow (about 1 minute per scan).
I've found that the delay is caused by scanadf waiting for the scanner lamp to warm up every time it starts and when scanadf exits the scanner lamp goes off. Applications like Xsane keep the lamp lit while the app is open so subsequent scans are immediate but I need command-line. Has anyone on this list seen or heard of a daemon that will keep the scanner "ready" and can be triggered to perform a scan when needed ?? I've had a play with saned but that doesn't come close. ( scanner is Epson Perfection 1260, O/S is Redhat 8.0 if that's of any use) Many thanks, nick@nexnix
