Write zplToSend ; writer. Everything else you are sending down looks good. First of all it wouldn’t make sense for Z64 to work if B64 doesn’t. ToBase64String b ; PrintThis string. Hi, has this method worked? He posts a LabView solution that can be opened up in LabView to send images down. Im using a TCP stream but by default the printers have it turned off.

Or knows where I am going wrong? You can further compress the image to reduce transmission time. First, you have to convert the image to a 1bpp bi-level image, then convert it to a hex-encoded string. In that case I’m not sure, as that’s the only way I’ve done it in the past.

I personally didn’t run it with my printer, I just used it to figure out the correct zebra s4m zpl 200dpi code so I could replicate it in my code.
I then started looking for the rest of the code I needed and stumbled upon the following: It says to either send it in Base64 or Hexadecimal, and I tried zebra s4m zpl 200dpi to no avail.
Jan 11 ’12 at Looks like I deluded myself into solving this. The second encoding, known as Z64, first compresses the zebra s4m zpl 200dpi using the LZ77 algorithm to reduce its size. Back to the drawing board.

Warren 1 4. I’ve tried a few variations, and a couple of methods for generating the CRC and calculating the ‘size’. Also, it seems ZPL defaulted to the uncompressed version zebra s4m zpl 200dpi the font after failing to load the compressed ones. But none seem to work and the download of the graphics to zebra s4m zpl 200dpi printer is always getting aborted. Read buffer, 0, buffer.
As it turns out, the compression functionality was not implemented in the printers I am using–the manufacturer is working on a firmware version zebra s4m zpl 200dpi handles compressed objects fonts or images.
Write zplToSend ; writer. The big thing that I was missing was padding my Hexadecimal code. But it doesn’t have a great deal more info. I ended up going with hex as well. WritePage baseStream ; gdipj. SizeOf docInfo ; RuntimeHelpers. PrinterHandle, buffer, read, out written throw new Win32Exception ; if written! The ZB64 format is basically not documented, and attempts to get more information from Zebra support have been fruitless.
