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.

NAME
lpstat - print cups status information SYNOPSIS
lpstat [ -E ] [ -H ] [ -U username ] [ -h hostname[:port] ] [ -l ] [ -W which-jobs ] [ -a [ destination(s) ] ] [ -c [ class(es) ] ] [ -d ] [ -o [ destination(s) ] ] [ -p [ printer(s) ] ] [ -r ] [ -R ] [ -s ] [ -t ] [ -u [ user(s) ] ] [ -v [ printer(s) ] ] DESCRIPTION
lpstat displays status information about the current classes, jobs, and printers. When run with no arguments, lpstat will list jobs queued by the current user. OPTIONS
The lpstat command supports the following options: -E Forces encryption when connecting to the server. -H Shows the server hostname and port. -R Shows the ranking of print jobs. -U username Specifies an alternate username. -W which-jobs Specifies which jobs to show, completed or not-completed (the default). This option must appear before the -o option and/or any printer names, otherwise the default (not-completed) value will be used in the request to the scheduler. -a [printer(s)] Shows the accepting state of printer queues. If no printers are specified then all printers are listed. -c [class(es)] Shows the printer classes and the printers that belong to them. If no classes are specified then all classes are listed. -d Shows the current default destination. -h server[:port] Specifies an alternate server. -l Shows a long listing of printers, classes, or jobs. -o [destination(s)] Shows the jobs queue on the specified destinations. If no destinations are specified all jobs are shown. -p [printer(s)] Shows the printers and whether or not they are enabled for printing. If no printers are specified then all printers are listed. -r Shows whether the CUPS server is running. -s Shows a status summary, including the default destination, a list of classes and their member printers, and a list of printers and their associated devices. This is equivalent to using the "-d", "-c", and "-v" options. -t Shows all status information. This is equivalent to using the "-r", "-d", "-c", "-v", "-a", "-p", and "-o" options. -u [user(s)] Shows a list of print jobs queued by the specified users. If no users are specified, lists the jobs queued by the current user. -v [printer(s)] Shows the printers and what device they are attached to. If no printers are specified then all printers are listed. COMPATIBILITY
Unlike the System V printing system, CUPS allows printer names to contain any printable character except SPACE, TAB, "/", and "#". Also, printer and class names are not case-sensitive. The "-h", "-E", "-U", and "-W" options are unique to CUPS. The Solaris "-f", "-P", and "-S" options are silently ignored. SEE ALSO
