0x1B, 0x41, 0 : A Get status, 2 byte command, 1 unknown byte.0x1B, 0x47 : G Short form feed, 2 byte command.Send 'footer data' of label (last packet of blob - MSG_MORE = false) 0x1B, 0圆E, 1, 0 : n Label index, 2 byte command, 16-bit value (meaning of index unknown).0x1B, 0圆8 : h Printer in 300x300 dpi text mode.0x1B, 0x43, 0圆4 : C Print-Density, 2 byte command, 1 byte value (0圆4 ^= normal).

0x1B, 0x73, 1, 0, 0, 0 : s Session-Counter, 2 byte command, 32-bit value (meaning of counter unknown).Receive reply from printer (32 bytes - see doc/cmd_status.md for status details).0x1B, 0x41, 1 : A Send a TCP packet containing 3 bytes (2 byte command, 1 unknown byte).Don't know what happens if this isn't considered!? ProtocolĮxample for printing a 272x252 bitmap to a 25mm X 25mm label with 300x300dpi. So the wrap around is at a byte boundary, and there are no unused trailing bits in the blob. I just testes this with a label width that is a multipel of 8. The bitmap blob seems to match the pbm P4 format (see ).

It ends in the lower right corner with bit 0 of the last byte.There is a wrap around at the end of each row.The next pixel (1st row, 2nd column) is followed by bit 6.It starts in upper left corner with bit 7 of the first bitmap-byte.The bits of the bitmap blob are mapped to label pixels row by row, column by column (Z) Among other things the width (number of columns) and height (number of rows) of the bitmap, the label length, print density, print quality. In a preceeding header some meta information are defined. The label itself is given by a bitmap 'blob'. These parameter are little endian encoded. Also there are commands, thatĮach command starts with 0x1B followed by a 'command selector byte' and optional parameter data.

The commands are similar as specified in LabelWriter 450 Series Printers Technical Reference Manual but not in all cases. The printer implements a kind of ESC protocol. This makes sense, because port 9100 is reserved for PDL (page description language)ĭata streams, used for printing to certain network printers. Findingsįor communiction with the LabelWriter Wireless TCP port 9100 is used. To make it short: Based on the information provided in the resouces noted above I managed it to figure out the majority of the TCP communication protocol.

So it was time for Wireshark to capture the communication between the DYMO's label creater software DYMO Label and LabelWriter Wireless. Nevertheless I still didn't have all required information to 'operatate' the LabelWriter Wireless out of my own application. SearchingĪround the internet ended up in two interessting projects whose sourcecode contains additional informaiton: The Reference Manual for LabelWriter 450 Series Printers had some useful information but not exactly that what I wanted to know. I get in contact withĭYMO's support and asked for a Reference Manual for LabelWriter Wireless but I got only the one for LabelWriter 450. LabelWriter 450 Series Printers Technical Reference Manual via Google but none for LabelWriter Wireless. Unfortunately there was little information for LabelWriter Wireless.

My starting point was the DYMO's LabelWriter SDK. I had the idea to print labels out of an (web)applicationĬontaining data like numbers and barcodes dynamically retrieved from a database. In addition it serves a site (which is using this REST-API) that allows label printing from by a web form:Ģ018 I bought DYMO's new wireless label printer ( LabelWriter Wireless). dymon_srv implements a webserver, that allows printing of labels through a REST-API.dymon_cli and dymon_pmb allows printing of labels from command line.Command line tools and printserver (webserver) for DYMO LabelWriter Wireless.
