Function Reference 4-43
pclWrite
Description
Writes MPCL packets to the Print subsystem.
You can send no more than one packet at a
time. It must be complete.
A batch packet starts a print job, which makes an asynchronous
call to the Print subsystem. After submitting a print job, the
application should call pclStatus in a loop, waiting until the
printer becomes free. See “Pausing While Printing” in Chapter
6 for more information.
Syntax
short far pclWrite(char far* lpchBuffer,
unsigned short usCount);
Parameters
lpchBuffer
A pointer to the data to write.
usCount
The number of bytes to write. The maximum size is
64K.
Return Values
0
Successful.
Non-zero
An error occurred. For errors between 703-793, The
operator corrects the printer condition. Then the
application must call pclClearError to reset the Motion
Control subsystem. Refer to the MPCL
Packet
