PCL 5 Printer Language Support
Summary:
This file provides support for the PCL 5 printer language when using the
USB Embedded Host Printer Client Driver.
Description:
This file provides support for the PCL 5 printer language when using the
USB Embedded Host Printer Client Driver.
There are several versions of the PCL printer language. This file is
targetted to support PCL 5. Unfortunately, printer language support is not
always advertised correctly by the printer. Some printers advertise only
PCL 6 support when they also support PCL 5. Therefore, the default value
for the LANGUAGE_ID_STRING_PCL string used in the routine
USBHostPrinterLanguagePCL5IsSupported() is set such that the routine will
return TRUE if any PCL language support is advertised. It is highly
recommended to test the target application with the specific printer(s)
that will be utilized, and, if possible, populate the
usbPrinterSpecificLanguage[] array in usb_config.c via the configuration
tool to manually select the printer language and its functional support.
Notes:
The PCL 5 coordinate origin is located at the top left corner of the paper.
The HP-GL/2 coordinate origin, however, is located at the bottom left corner
of the page. For consistency for the user, HP-GL/2 coordinate system is
adjusted to match the PCL coordinate system. This also matches the
coordinate system use by the Microchip Graphics library.
The black and white bit image polarity is 0=white, 1=black, which is
reversed from the Microchip Graphics Library polarity. This driver will
automatically convert the image data to the required format, as long as the
image data is located in ROM (USB_PRINTER_TRANSFER_FROM_ROM) or it is
copied from a RAM buffer (USB_PRINTER_TRANSFER_COPY_DATA). If the data is
to be sent directly from its original RAM location, the data must already
be in the format required by the printer language.
PCL 5 is not compatible with PCL 6; PCL 5 utilizes ASCII input, whereas
PCL 6 utilizes binary data. However, some printers that advertise support
for only PCL 5 do support PCL 6.
PCL 3 printers utilize many of the PCL 5 commands. The following
limitations exist with PCL 3:
* PCL 3 does not support vector graphics
* PCL 3 does not support image printing in landscape mode. The
page print will fail.
* Items must be sent to the page in the order that they are to be
printed from top to bottom. The printer cannot return to a
higher position on the page.
* PCL 3 does not support the USB_PRINTER_EJECT_PAGE command. Use the
USB_PRINTER_JOB_STOP and USB_PRINTER_JOB_START commands instead.

Function:
BYTE USBHostPrinterLanguagePCL5( BYTE address,
USB_PRINTER_COMMAND command, USB_DATA_POINTER data, DWORD size, BYTE transferFlags )
Summary:
This function executes printer commands for a PCL 5 printer.
Description:
This function executes printer commands for a PCL 5 printer. When
the application issues a printer command, the printer client driver
determines what language to use to communicate with the printer, and
transfers the command to that language support routine. As much as
possible, commands are designed to produce the same output regardless
of what printer language is used.
Not all printer commands support data from both RAM and ROM. Unless
otherwise noted, the data pointer is assumed to point to RAM, regardless of
the value of transferFlags. Refer to the specific command to see if ROM
data is supported.
Preconditions:
None
Parameters:
BYTE address - Device's address on the bus
USB_PRINTER_COMMAND command - Command to execute. See the enumeration
USB_PRINTER_COMMAND for the list of
valid commands and their requirements.
USB_DATA_POINTER data - Pointer to the required data. Note that
the caller must set transferFlags
appropriately to indicate if the pointer is
a RAM pointer or a ROM pointer.
DWORD size - Size of the data. For some commands, this
parameter is used to hold the data itself.
BYTE transferFlags - Flags that indicate details about the
transfer operation. Refer to these flags
* USB_PRINTER_TRANSFER_COPY_DATA
* USB_PRINTER_TRANSFER_STATIC_DATA
* USB_PRINTER_TRANSFER_NOTIFY
* USB_PRINTER_TRANSFER_FROM_ROM
* USB_PRINTER_TRANSFER_FROM_RAM
Return Values:
USB_PRINTER_SUCCESS - The command was executed successfully.
USB_PRINTER_UNKNOWN_DEVICE - A printer with the indicated address is not
attached
USB_PRINTER_TOO_MANY_DEVICES - The printer status array does not have
space for another printer.
USB_PRINTER_OUT_OF_MEMORY - Not enough available heap space to
execute the command.
other - See possible return codes from the
function USBHostPrinterWrite().
Remarks:
When developing new commands, keep in mind that the function
USBHostPrinterCommandReady() will be used before calling this function to
see if there is space available in the output transfer queue.
USBHostPrinterCommandReady() will routine TRUE if a single space is
available in the output queue. Therefore, each command can generate only
one output transfer.
Multiple printer languages may be used in a single application. The USB
Embedded Host Printer Client Driver will call the routine required for the
attached device.

/****************************************************************************
Function:
BOOL USBHostPrinterLanguagePCL5IsSupported( char *deviceID,
USB_PRINTER_FUNCTION_SUPPORT *support )
Summary:
This function determines if the printer with the given device ID string
supports the PCL 5 printer language.
Description:
This function determines if the printer with the given device ID string
supports the PCL 5 printer language.
Unfortunately, printer language support is not always advertised correctly
by the printer. Some printers advertise only PCL 6 support when they also
support PCL 5. Therefore, this routine will return TRUE if any PCL
language support is advertised. It is therefore highly recommended to test
the target application with the specific printer(s) that will be utilized.
Preconditions:
None
Parameters:
char *deviceID - Pointer to the "COMMAND SET:" portion of the device ID
string of the attached printer.
USB_PRINTER_FUNCTION_SUPPORT *support - Pointer to returned information
about what types of functions this printer supports.
Return Values:
TRUE - The printer supports PCL 5.
FALSE - The printer does not support PCL 5.
Remarks:
The caller must first locate the "COMMAND SET:" section of the device ID
string. To ensure that only the "COMMAND SET:" section of the device ID
string is checked, the ";" at the end of the section should be temporarily
replaced with a NULL. Otherwise, this function may find the printer
language string in the comments or other section, and incorrectly indicate
that the printer supports the language.
Device ID strings are case sensitive.
