Hi Well I have updated to GutenPrint and tried to print but all that happens is that the printer flashes and doesn't produce any output. I have been using a CANON i550 with Gimpprint which worked with the S800 definition file. I went through the following process: - Backed up GimpPrint including the drivers and deleted the copies of GEMPrint, GPSetup and GP Printer definitions within !Printers. -Copied over the new versions of GEMPrint, GPSetup, GPDriver2 and definitions into !Printers. -Loaded the new GP2 S800 definition file into !Printers and set it up including using Ian Hamilton's software to select USB. - Saved everything and reset the machine. - I then tried print out and it start the GP2 progress but nothing comes out of the printer. - Repeated this for the orignal GimpPrint version and this still works. - Tried IP4000 file but still the same. Any suggestions welcome including any debug information that i can collect. Thanks Doug -- Using a Iyonix PC and RISC OS 5.13, the thinking persons alternative operating system to Microsoft Windows.
