OverrideThroughput in the page device

This page applies to Harlequin v13.1r0 and later; and to Harlequin MultiRIP but not Harlequin Core.

OverrideThroughput is a page device key boolean (default false) that ensures use of single-if mode even if the output controller is active. Even if the output controller is (throughput system) is active throughput is considered as the destination for output, OverrideThroughput determines whether it should output directly instead.

Typically, OverrideThroughput is set in a plugin’s PostScript code, often in response to a checkbox in the Device Type’s Configure device dialog within the Page setup. For example, if the plugin introduces a plugin parameter MyPluginDirectOutput, plugin PostScript, or a page feature might contain:

            <<
            /OverrideThroughput
            currentpagedevice /MyPluginDirectOutput get
            >> setpagedevice

You can submit some special jobs to the RIP that bypass the normal queuing mechanisms (that is, not appearing in the input queue), but create a page buffer in the normal way. You can use a job, page feature, or a plugin PostScript file that sets the page device key /OverrideThroughput to true.

            <<
            /OverrideThroughput true
            >> setpagedevice

This tells the RIP to output the page in single-if mode even if the RIP is globally set to multiple mode.
