Asynchronous Terminals and Printer Processes Programming Manual

PRINTER PROGRAMMING CONSIDERATIONS
Path Errors
Path errors 210 through 231 indicate that the operation failed
at some indeterminate point. The paper might have moved. The
approach to the error depends on the application. If the
operation is critical, such as printing payroll checks, the check
should probably be canceled and a message sent to the operator.
Otherwise, the line can be reprinted and might be duplicated.
