Hi,

Nice progress in the UI! The program now detects my HP Color LJ Pro MFP 3302 properly but it indeed still fails when I try to scan

"Failure when receiving data from the peer! (56)
File: AirScanner4.hws [current line: 589 - In function: perform}

though (and completely quits the program then)

On a positive note, it indeed starts to get data with PreScan and it gets displayed in the preview area, albeit not from the single sheet feeder.

Definitely progress, great !
