HP Color LaserJet CP3525 Series Printers - Software Technical Reference

Postscript Passthrough – PS Universal Print Driver only
Postscript Passthrough 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
software programs with Postscript Passthrough enabled, because such programs send postscript
information to the product that cannot be controlled by the driver. Other programs might print using these
options without problems. Select Disabled and print the document again if you encounter problems.
NOTE: In some cases, disabling Postscript Passthrough can cause unexpected results within a
software program.
JPEG Passthrough – PS Universal Print Driver only
JPEG Passthrough is set to Auto by default. When set to Auto, JPEG Passthrough detects the printer
connection type and either disables JPEG Passthrough for network (TCP/IP) connections or enables
JPEG Passthrough for parallel (LPT), DOT4, and USB connections.
Select Disable to print JPEG images as bitmaps. This results in faster printing.
Select Enable to print JPEG images as JPEGs (JPEG passthrough).
Mopier Mode
The multiple-original print (mopy) function is an HP-designed feature that produces multiple, collated
copies from a single print job. Multiple-original printing (mopying) increases performance and reduces
network traffic by transmitting the job to the product once, and then storing it in memory or the hard disk.
The remainder of the copies are printed at the fastest speed. All documents that are printed in mopier
mode can be created, controlled, managed, and finished from the computer, which eliminates the extra
step of using a photocopier.
The HP Color LaserJet CP3525 Series supports the transmit-once mopying feature when the Mopier
Mode: setting on the Device Settings tab is Enabled.
When you use the HP PS Universal Print Driver or the HP PCL 5 Universal Print Driver, mopying is
performed in one of two ways: either through the software or through the product hardware. When
mopier mode is enabled, mopying takes place through the product hardware. 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 directing the product to make the specified number of copies.
When you disable the mopier, you are not necessarily disabling multiple collated copies, which the driver
can still perform through the software rather than the product hardware (the mopying path that is disabled
when you change the Mopier Mode setting to Disabled). However, a multiple-copy print job that is sent
when the mopier is disabled loses the advantage of transmitting the print job once, because the job is
sent through the network for each collated copy.
Mopier mode and collation
Mopying and collating print jobs are independent but closely related functions. Mopying, the ability to
send original print jobs to the product, is performed by the print driver. Collating can be 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.
Control collation through the print driver by selecting or clearing the Collated check box on the
Advanced tab. Click Copy Count under the Paper Output setting. You can clear the check box, which
