I have the star micronics mpop. I have read the documentation (http://www.starmicronics.com/support/mannualfolder/starprnt_cm_en.pdf) Section 2-8 states that you can write to the blank code page. I have followed these instructions but I am still unable to get it to print as intended. I contacted support but they basically told me to use trial and error as they didn't know.
It always seems to prints a string of characters. Below is the sample code I am using, just for testing i'm sending a solid block for font A and zero data for font B.
[commands appendBytes:
"\x1b\x1d\x3d\x00\x30"

Any help to get this working would be greatly appreciated.
I have finally managed to get this to work using the command
ESC GS = n1 n2 da1 da2...
to save a character and the commandEsc % = n
to print the character.The example below will save a character to position 7F on the blank code page. This should be done at the start of each app startup as it is stored in RAM, not NV.
It is also a good idea to switch back to the normal code page after this otherwise you will have some weird side effects. This can be done using using the command Esc GS t n. Where n = 0.
