Hi,
What's an example of a single command--"set
the label size", for example. Do you know of any way to
run it in isolation? Is it a "command-line command", or,
simply a documented (COM?) programming interface?

consider for setting the label size command as F (topleft
coordinates,bottom cordinates). its a 3 byte data sent to the printer.

For response consider prinetr status PC 74, need to send two bytes of
data, printer responses the status with 8 bytes.

As far as now , I have only commands set, no printer?But I need to
be ready with idea how it can be done.

So I m using a similar printer and its command set, So if this is
automated, only commands needs to be changed. Currently for this
printer, comamnds are sent through printer driver.

3.Now I m trying to send comamnd from tcl to serial printer ?but am
unable to do?
set fh [open com2: RDWR]

fconfigure $fh -blocking 0 -buffering none \
-mode 9600,n,8,1 -translation binary -eofchar {}

puts $fh 1B 40 //command to initialize printer
bad argument "40": should be "nonewline"


Is this is the proper way to send command to serial printer?For status
response,how can I read it from the printer?


Thanks and Regards
