FULL PRODUCT VERSION :
java version "1.7.0_147-icedtea"
OpenJDK Runtime Environment (IcedTea7 2.0) (7~b147-2.0-1)
OpenJDK 64-Bit Server VM (build 21.0-b17, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Debian Wheezy 3.0.0-2-amd64 #1 SMP Fri Oct 7 20:48:45 UTC 2011 x86_64 GNU/Linux

EXTRA RELEVANT SYSTEM CONFIGURATION :
The system is linked with a network printer (Brother filterHL5350DNLT).
This printer is a ps-based printer and is configured in cups correctly (so the options like tray and duplex work when invoked through cups)

A DESCRIPTION OF THE PROBLEM :
The problem is that when I try to submit a printjob to the printer (described in additional config) I always get a message on the printer about "Incorrect size".
When I invoke the printer, I always specify a tray - when I do not specify a tray, tray 1 is always used and the printing works.

I've been debugging this issue for a long time and I came out at sun.print.PSPrinterJob.printExecCmd line 1553 where I could find the code: execCmd[n++] = new String(options);
In the man-page for LPR I could find that options should be passed with the "-o" prefix (like done on line 1573 in the same method and also in UnixPrintJob does this correctly).
But when this is solved, I believe there is still a problem because I couldn't find where "mOptions" (global var in PSPrintJob) is assigned to a correct value.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) take a printer that supports tray-based printing (if possible the same printer)
2) create a small app that uses java.awt.print.PrinterJob to print something to tray 2
3) run the app and validate the result

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
the printer takes a sheet from tray 2 and prints the content on it
ACTUAL -
the printer goes in error-mode with the message "incorrect size".

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
            PrinterJob job = PrinterJob.getPrinterJob()
            job.setPrintService(getPrintService());
            job.setPrintable(printable);

            MediaTray trayNumber = ... //one of the selected trays from the supported attributes list

            PrintRequestAttributeSet reqAttrSet = new HashPrintRequestAttributeSet();
            reqAttrSet.add(trayNumber);

            job.print(reqAttrSet);
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
This workaround is only possible if you own the code that invokes the printjob:
using DocPrintJob printerJob = printService.createPrintJob(); (so the print-features in javax.print)

but this is impossible when using the a framework like JasperReports
