Thank you for your help, but the method shown did not work.
I have managed to install the iP1900 printer by the following method.
1 I started the “printer advanced setup” and selected printer not shown, opened the wi ndows driver list and noted the entry for the printer was “Canon iP1900 series”
2 Then checked on the desktop and printer name was “ Canon Inkjet iP1900 series” so I went to sharing set up and deleted “ inkjet"
3 Restarted the laptop and used “printer advanced setup” entered new port as
“\desktop\Canon Inkjet iP1900 series” went select driver, and then used “ use existing driver” option, then installed printer and printed test page.
Hope this may be of help to someone else.
