The Harlequin Extended Error Handler
This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP
Most versions of the Harlequin RIP have access to a text-based standard output channel, and a large proportion of copies of the RIP are used for high resolution output where extended error reporting on the output medium is not a desirable option. Harlequin have therefore released an extended error handler which shows all its results by default on the standard output channel. The information reported is sufficient to allow a PostScript programmer to isolate most problem code as rapidly as possible, and there are some configuration switches to change the amount of information reported.
It is assumed that the reader will be familiar with PostScript language programming, and with the normal error handling procedure in a PostScript interpreter (as described on pages 100-101 of [RB2]).
