CUPS printing and control escape codes

I ported application from SysV to Linux and run into troubles with printing.

Application uses lp and HP JetDirect-based printers, it inserts HP control codes in the file and uses plain lp -d dest doc-file command to print it.

The Linux (Ubuntu 8) has CUPS system, which I am not familiar with. I added JetDirect's IP to the hosts and used The UNIX and Linux Forums - Learn UNIX and Linux from Experts interface to add the printer, its model was in the list (this is HP P2015n) and the test print worked like a charm. but when I run app and print from it the control codes in the file body are not recognized as a control sequence characters, but rather as a plain text and printed along with the actual text. I captured the file from the app and tried to print it with -o raw option,
Code:
lpr -P lpr5 -o raw prtfile

but result is the same, control codes are treated as a part of the text.

Any help on how to tune up this CUPS would be appreciated.

cupsenable(8)							    Apple Inc.							     cupsenable(8)

NAME
cupsdisable, cupsenable - stop/start printers and classes SYNOPSIS
cupsdisable [ -E ] [-U username ] [ -c ] [ -h server[:port] ] [ -r reason ] [ --hold ] destination(s) cupsenable [ -E ] [-U username ] [ -c ] [ -h server[:port] ] [ --release ] destination(s) DESCRIPTION
cupsenable starts the named printers or classes. cupsdisable stops the named printers or classes. The following options may be used: -E Forces encryption of the connection to the server. -U username Uses the specified username when connecting to the server. -c Cancels all jobs on the named destination. -h server[:port] Uses the specified server and port. --hold Holds remaining jobs on the named printer. Useful for allowing the current job to complete before performing maintenance. -r "reason" Sets the message associated with the stopped state. If no reason is specified then the message is set to "Reason Unknown". --release Releases pending jobs for printing. Use after running cupsdisable with the --hold option to resume printing. COMPATIBILITY
Unlike the System V printing system, CUPS allows printer names to contain any printable character except SPACE, TAB, "/", or "#". Also, printer and class names are not case-sensitive. The System V versions of these commands are disable and enable. They have been renamed to avoid conflicts with the bash(1) build-in com- mands of the same name. The CUPS versions of disable and enable may ask the user for an access password depending on the printing system configuration. This dif- fers from the System V versions which require the root user to execute these commands. SEE ALSO
