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
lpr - print files SYNOPSIS
lpr [ -E ] [ -H server[:port] ] [ -U username ] [ -P destination[/instance] ] [ -# num-copies [ -h ] [ -l ] [ -m ] [ -o option[=value] ] [ -p] [ -q ] [ -r ] [ -C/J/T title ] [ file(s) ] DESCRIPTION
lpr submits files for printing. Files named on the command line are sent to the named printer (or the default destination if no destination is specified). If no files are listed on the command-line, lpr reads the print file from the standard input. THE DEFAULT DESTINATION
CUPS provides many ways to set the default destination. The "LPDEST" and "PRINTER" environment variables are consulted first. If neither are set, the current default set using the lpoptions(1) command is used, followed by the default set using the lpadmin(8) command. OPTIONS
The following options are recognized by lpr: -E Forces encryption when connecting to the server. -H server[:port] Specifies an alternate server. -C "name" -J "name" -T "name" Sets the job name. -P destination[/instance] Prints files to the named printer. -U username Specifies an alternate username. -# copies Sets the number of copies to print from 1 to 100. -h Disables banner printing. This option is equivalent to "-o job-sheets=none". -l Specifies that the print file is already formatted for the destination and should be sent without filtering. This option is equivalent to "-o raw". -m Send an email on job completion. -o option[=value] Sets a job option. -p Specifies that the print file should be formatted with a shaded header with the date, time, job name, and page number. This option is equivalent to "-o prettyprint" and is only useful when printing text files. -q Hold job for printing. -r Specifies that the named print files should be deleted after printing them. COMPATIBILITY
The "c", "d", "f", "g", "i", "n", "t", "v", and "w" options are not supported by CUPS and produce a warning message if used. SEE ALSO
