This will build the filter. <P>Move the filter to the CUPS installed directory, typical install is /usr/lib/cups/filter. <P><B>Creating a .ppd file</B>: <P>After the filter is properly created on put into the proper directory, the .ppd file must be made. <P>This is done by running the GenerateOmniPPDs program. This also resides in the Omni/CUPS directory. This step assumes that Omni is properly installed or the driver files used by Omni are in the LD_LIBRARY_PATH. The syntax for this is: <P>GenerateOmniPPDs Omni_DeviceDriver_Name > Omni_DeviceDriver_Name.ppd <P>This will create a named .ppd file for the Omni driver you wish to support. This file will need to be moved to the /etc/cups/ppd/ directory. <P><B>Create a printer:</B> <P>Follow the documentation for creating a printer for use with CUPS provided by CUPS. <P><FONT SIZE="7">Basic CUPS to Omni Interface object layout</FONT> <P><FONT SIZE="5"> <IMG SRC="3ca8ac86.jpg" ALIGN="BOTTOM" BORDER="0" TARGET="_top"></IMG></FONT> <P><FONT SIZE="5">Options:</FONT> <P>The available options for a particular driver is made available to the user by using the lpoptions command. The syntax is: <P>lpoptions -d Printer1 -l <P>This will list the available options defined for the driver that is currently running for the CUPS printer, here defined as Printer1. <P><FONT SIZE="5">Forms:</FONT> <P>Omni utilizes a vast number of forms for communicating to the driver. These form names are prefixed with FORM_ and are given with the following command syntax: <P>lp -o <B>media=FORM_A4</B> -d Printer1 infile.ps <P>The above command will select A4 forms. <P>The listing of available forms can be listed using the lpoptions command - PageSize values. <P><FONT SIZE="5">Media Type Selection:</FONT> <P>You can utilize other media types than just plain paper. <P>To utilize other media types use the following command line: <P>lp -o <B>media=MEDIA_SPECIAL_720</B> -d Printer1 infile.ps <P>Or the combined form/media command of: <P>lp -o <B>media=FORM_A4,MEDIA_SPECIAL_720</B> -d Printer1 infile.ps <P>These options are listed using the lpoptions command - MediaType values. <P><FONT SIZE="5">Monochrome Selection:</FONT> <P>Most of the Omni color devices also support monochrome. To utilize monochrome using CUPS and Omni the following command arguments need to be used: <P>lp -o <B>ColorModel=Gray</B> Printer1 infile.ps <P>This will tell Omni and CUPS to generate monochrome output. <P>Omni color devices will utilize color as default so no command line will be needed for standard (default) color output. These are listed using lpoptions command - ColorModel values. <P><FONT SIZE="5">Resolutions:</FONT> <P>The resolutions can be set. The resolution value is also has the RESOLUTION_ prefix. <P>The resolution is set by the following command: <P>lp -o<B> resolution=RESOLUTION_720_X_720</B> -d Printer1 infile.ps <P>This will set the resolution to one of the available ones that was shown when using the lpoptions command - Resolution values. <P><FONT SIZE="5">PrintMode:</FONT> <P>The drivers can change between different print modes other than monochrome such as CMY, CMYK, and CcMmYK based on the printer configuration. <P>The following command can be used to set the output print mode: <P>lp -o <B>printmode=PRINT_MODE_CcMmYK</B> -d Printer1 infile.ps <P>These values are not listed using the lpoptions command but standard ones are defined as: <P>PRINT_MODE_1_ANY - Monochrome <P>PRINT_MODE_24_CcMmYK - Six color with light cyan and light magenta <P>PRINT_MODE_24_CMYK - Standard four color <P>PRINT_MODE_24_CMY - Standard three color (minus black) <P><B>NOTE:</B> <P>PRINT_MODE_1_ANY should not be selected if CUPS is not set for gray using the ColorModel=Gray command line parameter. <P>Other selections for Omni can be input the same way via CUPS lp command. </BODY> </HTML>
