Adding Human Readable Text

To be compatible with the original HP package, the PCL fonts in this package do not have human readable text characters. It is easy to add text with a separate print command. The following example select the default font (command <esc>(3@ ), and print the human readable below the barcode:

fprintf(prn, "\0x1B(0Y\0x1B(s0p4h12.0");
fprintf(prn, "*PN18906*");
fprintf(prn, "\0x1B(3@\n");
frpintf(prn, "PN18906");
