mopying takes place through the product hardware by default. One copy of a multiple-page print job is transmitted once through the network to the product, together with a printer job language (PJL) command that directs the product to make the specified number of copies. When you disable the mopier, you are not necessarily disabling mopying, which the driver can still be performed through the software rather than through the product hardware (the mopying path that is disabled when you change the Mopy Mode setting to Disabled). However, a multiple-copy print job that you send with the mopier disabled loses the advantage of transmitting the print job once, because the print job is sent through the network the same number of times as the number of copies selected. Mopier mode and collation Mopying and collating print jobs are independent but closely related functions. The print driver performs mopying, which is the ability to send original print jobs to the product. Collating is controlled by either the print driver or the document software program. The mopying mode is selected by default in the driver, and can be disabled by changing the Mopier Mode setting on the Device Settings tab to Disabled. You can control collation through the print driver by selecting or clearing the Collated check box on the Advanced tab. You can clear the check box, which is available only when the Copy Count option is set to more than 1 copy, to allow the software program to control collation. To receive uncollated multiple copies of a print job, you must clear the Collated check box and make sure that the software program collation feature is not selected. The following table shows the relation between mopier mode settings and collation settings in the software program and the driver. The first three columns show the settings; the last column, "Expected result," shows how a three-page print job would appear.

It is enabled by default, and must be enabled for most print jobs. Postscript Passthrough provides additional capabilities for some software programs when printing to a Postscript driver. Options such as Watermarks, N-up, and booklet printing might not print correctly from some programs with Postscript Passthrough enabled, because such programs send Postscript information HP unidrivers HP PCL 6, HP PCL 5e, and PS emulation unidriver features 219
