quote "/copy /c Directly copy from scanner to printer, using settings provided or default settings
...
/printer "printer name" Specify the name of the printer between inverted commas. If not provided, the system default printer is used"
source: icopy "readme"
So when press the scan button, icopy called with arguments:
ProcMon>"PID: 3936, Command line: d:\Programs\ICopy\iCopy.exe /copy /Printer "Canon iP3300" /StiDevice:{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}\0000 /StiEvent:{9BF2BAA8-C6BA-451B-9A53-C7369531F1EF}"
icopy_log>"Command Line parameters: /copy /Printer Canon iP3300 /StiDevice:{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}\0000 /StiEvent:{9BF2BAA8-C6BA-451B-9A53-C7369531F1EF} "
But still printed on def printer.
PS
WIN XP SP3 x86
iCopy 1.6.0.211
Canon MF 3110 as scanner and Canon IP 3300 as desired printer, Aficio FX16 as defaul printer in system.
initial bug fixed: When I add values of cmdline to the registry in a few places I have different command line (different sequence of commands). If wherever they appear - select the same, the command string to the right.
but /printer "Canon iP3300" stil not affected
