Canon prints start with escape followed by '[K' so maybe the initial
character is lost.

This suggests the initial Printer$Path is incorrect which can happen with
!Printers. Maybe fixable by manipulating the 'Settings' file (or
certainly by running PrintSpool if this is the problem). Any prints that
use the Wimp print protocol message system should work without
intervention.

Just clicking it even though it is already selected should be enough.

Most likely Printer$Path is pointing to 'null:'.
