javax.print.attribute.PrintRequestAttributeSet options ignored by Printer

Question

Hi - I have to print a file (plain text) using javax.print api's. I am able to lookup the printer and submit a print job. But i am able to only print one copy of the file. Below is the code i have been using.

None of the options/attributes i specified using the PrintRequestAttributeSet is recognized by the printer. Though i specify 2 copies to print, the printer only prints one copy. Am i doing anything wrong here?

Printer used: Canon iR5050 PCL6
