func init() { http.Handle("/view", appHandler(viewRecord)) } With this basic error handling infrastructure in place, we can make it more user friendly. To do this we create an appError struct containing an error and some other fields: type appError struct { Error error Message string Code int } Next we modify the appHandler Very annoying and embarrassing, but I'm sure it is something simple.

Remove the Alpha printer using the Windows controlpanel go inside the alpha executable folder, and find the exe for reinstalling - most likely in x86 program files\a5v11\amyuniv4\installlamyuniprinters then go back to I want to deal with the low-hanging fruit that gives the biggest benefit for the least work (and least complexity!), not minimise every conceivable bit of redundancy in a stack trace.

Please try the request again.

Stand alone laptop connected to a Dell laser printer with a USB cable, have tried two different printers and does the same with both. The system returned: (22) Invalid argument The remote host or network may be down. Some ideas: give the error handler a pretty HTML template, make debugging easier by writing the stack trace to the HTTP response when the user is an administrator, write a constructor Hopefully this will solve Tony's issue.

If I were you, I'd remove oneNote first. type errorString struct { s string } func (e *errorString) Error() string { return e.s } You can construct one of these values with the errors.New function.
