Help! - I need to send an set of escape control codes to an Epson printer. It all appears to be ok until I need to add hex 00 as a byte at the end of a control code. As the code sequence needs to end in this value I would greatly appreciate any help you can give.

Regards Graham

It might be a silly question... have you tried to print $ESC_CONTROL_CODE + CHAR(0) already?

Where...

$ESC_CONTROL_CODE = CHAR(27) + $ANY_CONTROL_CODE.

Hi - thanks for the swift reply. I have tried to send the character as the end byte of the control string. All the other characters sent arrive at the printer but the 00 sequence does not appear to. If I send the output to a file and not the printer then I can 'see' the 00 is missing. Weird as 01 will work!

I've found that when sending to printer through the client, the CHAR(0)s disappear. But when printing directly from the kernel, it's OK.

I guess it's a deficiency in Pro-IVs client-server protocol.

Hi all,

I am a bit curious, how's the different by printing thru client / printing thru kernel? How to acheive both of them?

Regards,

Vol
