Finally, this application only recognizes Hewlett-Packard products, so every printer in your network may not be compatible with this application.

You will need to ensure you have the latest ICA driver installed on your PC for the software to work. There are some drawbacks to this application.
At the same time, performance has been optimized to ensure you get the highest-quality scanned documents. The recent upgrades to the software bring improved stability.
The sophisticated software recognizes both text and automatically detects images in a document. Process multi-page documents at one time or just a one-page. One example of this is if you are scanning a multiple page report, rather than create ten one page documents, your printer can be set up to always create one file. You can save time by programming it to perform functions. The outcome is a professional-looking document that can be viewed on any device. It scans text and images and replicates it into a digital file format.

This is an easy to use utility that quickly scans documents and allows you to save them as PDF files. Manage incoming documents by scanning them to PDF files.Ĭreated by HP, Easy Scan allows people who have Hewlett-Packard multifunction printers and scanners to manage their incoming documents. To avoid problems with the PDF files created by this software end users working with the HP Smart Document Scan software should ensure the paths to the scanned image files are far less the 127 characters.The official app for HP printers and scans. This practice does not guarantee that all XObjects in the file will have unique names. Using the file path as the XObject name is a bad practice especially where very long path names can be truncated. This results in each XObject in the file having a unique name. When creating names for XObjects it is common practice to use a short unique string followed by an incremental counter. This is very easy to locate within the HP files by simply opening the file using a text editor. Because this is now an invalid hex character at the end of a name object it produces the error “non-hex character in a hex string”. At the end of the name you can see ‘#2’ I’m assuming this should be ‘#20’. The name object above was truncated between two hex digits. I have removed the center of the name object for clarity.
Following is an example of what is sometimes produced: The PDF 1.2 Reference states “Any character except null () may be included in a name by writing its two-character hex code, preceded by #.” It is permissible for hex strings contained within angle brackets () to have an odd number of hex characters but, # hex character within name objects must always be two hex characters.īecause the extremely long XObject name uses a file path, coupled with truncating the file path at 127 characters the resulting PDF file can sometimes be malformed. If the path contains a space character it is placed in the Name object as ‘#20’. For long path names the HP software simply truncates the path at 127 characters. On some systems a file path can be quite long. Apparently, within the HP Smart Document Scan software the programmer is using the path to the image file as the Name of the image XObject when creating the PDF file.
The use of # hex values were not part of PDF 1.0 # hex values in Name objects were introduced in PDF 1.2. The first problem we found is located in /Name objects which contain ‘#xx’ hex values. The version number of the PDF files produced is PDF 1.0. It appears that the HP Smart Document Scan software is only included with the HP Scanjet 7800 Scanner and the HP Scanjet 8350 & 8380 scanners. Recently we have received a couple of malformed PDF files produced by the HP Smart Document Scan software.
