Bitmap printing ESC/POS commands in 2021


The software i'm maintaining has been churning along printing bitmaps via ESC *.
Recently i had to make some upgrades on another component and ended up using GS v 0.

I find ESC * to be convoluted and hard to use, whereas GS v 0 is considered obsolete. So the question is twofold:


Solution

  • The EPSON document is as follows.
    Obsolete Commands - TM Printer ESC/POS Command

    Both are described as being substitute by command groups starting with GS(L/GS8L.
    GS ( L / GS 8 L - TM Printer ESC/POS Command


    However, some vendors other than EPSON and even EPSON may not support it depending on the printer model(For example, dot printer).
    In such cases, ESC * is considered to be in active use.
