Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Re: Sending control codes to a printer

    I think that you may be on the right track ... he says with hopeful optimism ... but "test" becomes something else.

    I will try just the 1B and see what happens. If that works then I may have to send each code as an individual.

      Re: Sending control codes to a printer

      You can experiment in the interactive to see the output string.

      Code:
      ? chr(hex_to_dec("1B"))+chr(hex_to_dec("70"))+chr(hex_to_dec("00"))+chr(hex_to_dec("32"))+chr(hex_to_dec("F9")) 
= "p2�"
      Not sure about the 1B but the rest should look like what the Epson docs say if the code is correct.

      And you can see what the decimal sequence is

      Code:
      ? ""+hex_to_dec("1B")+" "+hex_to_dec("70")+" "+hex_to_dec("00")+" "+hex_to_dec("32")+" "+hex_to_dec("F9") 
= "27 112 0 50 249"

        Sending individually does not work either. Can anyone reading this saga get a hold of Jim Chapman and request a SEND_TO_USB_STRING ??

          What model is your Epson? Most of the codes I saw googling use 250 rather than 249.

            Re: Sending control codes to a printer

            Found several sites where the codes are shown with commas between the codes so you might try

            chr(hex_to_dec("1B"))+chr(44)+chr(hex_to_dec("70"))+chr(44)+chr(hex_to_dec("00"))+chr(44)+chr(hex_to_dec("32"))+chr(44)+chr(hex_to_dec("F9"))



            Also found.

            I did notice that the code you have has a zero on it though. This is sometimes a problem depending on the Windows operating system and how it interprets the code numbers. Basically its using decimal numbers to represent the code and the number zero is not recognized as a decimal number. You have to use the ASCII code for the zero which is "48" so your code should actually be
            27,112,48,25,250
            Try this code and let me know how it goes.
            So you might try

            chr(hex_to_dec("1B"))+chr(hex_to_dec("70"))+chr(48)+chr(hex_to_dec("32"))+chr(hex_to_dec("F9"))
            and/or same with commas as above.
            There can be only one.

              Re: Sending control codes to a printer

              Hello Stan,

              You are the man!!!

              The code string that I was using was given to me was by way of my printer supplier but the one you provided for the TM-T88V WORKED!!!

              The code that I ended up using follows:

              dim file_pointer as P
              dim text as C
              dim cnt as N

              file_pointer = file.create("\\Gene-pc\receipt", FILE_RW_SHARED)

              text= chr(27) + chr(112) + chr(48) + chr(55) + chr(121)
              file_pointer.write(text)
              file_pointer.flush()

              file_pointer.close()

              For those that need this; Gene-PC is the name of your PC and receipt is the name of your printer.

              Thanks to one and all!

              Regards,

              Gene FitzPatrick

                Re: Sending control codes to a printer

                Glad you got it working. Google is our friend. A printer supplier who gave you 1B 70 00 32 F9 is not.

                And a hearty pat on the back to Jacob.

                Don't know if is any great benefit but if you use that code in multiple places you might want to make it a function and call it where needed.


                drwr_open("\\Gene-pc\receipt")

                The logical return value would tell you if the function executed completely if you wanted to check it.

                Code:
                FUNCTION drwr_open AS L (unc_prtr as C)
drwr_open = .F.	
dim file_pointer as P
dim text as C
dim cnt as N
file_pointer = file.create(unc_prtr, FILE_RW_SHARED)
text= chr(27) + chr(112) + chr(48) + chr(55) + chr(121)
file_pointer.write(text)
file_pointer.flush()
file_pointer.close()
drwr_open = .T.
END FUNCTION

                  Re: Sending control codes to a printer

                  Thank you Stan. I am doing just that and then some. Since I intend to provide this as part of my point-of-sale system, I am working on making this generic so that it will be usable by any user regardless of what printer they have (with the proper codes of course :-) ).

                  Regards to all,

                  Gene
