Okay, that is interesting.

There's a simple check for this in openjdk6, I will make a patch for
removing it after I make sure nothing is going to go wrong elsewhere in
the code if X > Y doesn't hold true.

Title:
  Java is not able to read landscape-oriented paper sizes (like Ledger) in PPD files

Bug description:
  Binary package hint: cups

The Ledger paper size is incorrectly defined in many printers' PPDs. This causes significant printing problems in Java applications.

The Ledger paper size is defined as follows. For comparison the Legal size is included as well:

*PageSize Ledger/Ledger: "<</PageSize[1224 792]/ImagingBBox null>>setpagedevice"                                                                                                                
*PageSize Legal/US Legal: "<</PageSize[612 1008]/ImagingBBox null>>setpagedevice"

Notice how in the Ledger case, the width is specified as larger than the height. This is the only such entry in the entire file. 

When the JRE parses the PPD to find paper sizes, it chokes on that entry and raises an exception:

IPPPrintService>>  error creating CUPSPrinter e=java.lang.IllegalArgumentException: X dimension > Y dimension

This exception is normally silently ignored. It can be seen by enabling debugging with the following code. Note this is a proprietary API and not guaranteed to work on all JDK versions. It was tested on openjdk-6-jre 6b09-0ubuntu2.

sun.print.IPPPrintService.debugPrint = true;

When this happens, parsing page sizes is aborted, and an empty list of paper sizes results. The JRE then adds a single entry corresponding to the default paper size on the system. For instance on US systems the only paper size added is Letter, and A4 on european ones. This results in the inability to print anything that doesn't use the default paper size.

This bug is in the postscript.ppd file, which has extended to many other printers. A trivial way of testing it is installing cups-pdf, which carries a PPD with the same bug. On my system, "grep -r '1224 792' /usr/share/ppd | grep PageSize  | wc -l" suggests 238 printers are affected.

Reproduction:

$ sudo apt-get install cups-pdf
$ javac DumpPrintInfo.java
$ java DumpPrintInfo

Only one paper type will be listed for the PDF printer:
                class javax.print.attribute.standard.Media
                        na-letter
                class javax.print.attribute.standard.NumberUp


$ sudo sed -i 's/1224 792/792 1224/g' /etc/cups/ppd/PDF.ppd

$ java DumpPrintInfo

                class javax.print.attribute.standard.Media
                        Custom
                        jis-b4
                        b
                        iso-c3
                        jis-b3
                        iso-a2
                        jis-b0
                        jis-b0
...
