HP Designjet Printers - Landscape Images Printing in Portrait Orientation from AutoCAD 2007 and 2008
An issue has been identified when printing landscape pages that should fit exactly on the roll loaded on the printer. These pages are printed in portrait orientation instead, resulting in more paper used by the printer and the need to trim the right margin.
So far, this issue has been seen in AutoCAD 2007 and 2008, but other applications could be affected, as well. This document describes the symptoms of the issue, its causes and the available workarounds.
Issue description and symptoms
This issue is affecting the following driver versions:
There are two possible ways to see the issue:
The root cause of the issue has been identified as an issue with figures being ‘rounded’ in the interaction between the HP driver, the operating system and AutoCAD. Because of this issue, all landscape pages are considered to be one pixel larger than they actually are. This is no issue as long as the page is smaller than the loaded roll, but when the original page size and the size of the roll match exactly, it has the following effects:
We are working on a definitive solution for this issue which should be available in the next driver release for all affected products. Currently available workarounds are:
The driver for the HP Designjet T and Z series obtains information about the loaded paper using bidirectional communication with the printer, so rotation is always done comparing it to the currently loaded paper roll.
With these drivers, there is a workaround that would apply for all pages (including 42 inches wide pages). The workaround consists on disabling the bidirectional communication with the printer and setting the driver’s queue up so that it considers that the loaded paper is 44 inches wide.
To do that:
After doing that, the driver will stop looking for loaded paper information on the printer and will always consider that the loaded paper is 44 inches wide, hence, rotating or printing in landscape any drawing that would fit on 44 inches paper (including all sizes used normally in CAD).
Appendix: How to downgrade driver 6.19 to 6.17
The automatic Windows printer installation process (the Add printed wizard) does not work when downgrading drivers. If you attempt to install a printer with a driver version which is older than the one installed on the system, the Wizard will find out that the DLLs of the existing driver are newer than the ones that are being copied and will not overwrite them. No matter which options are selected during the installation process, the result will always be the same: the most current version of the driver will be kept.
The only way to downgrade a driver is to manually remove the current driver and then, to install the older version on a ‘clean’ system.
The steps to do that are the following:
