Dear Appeon:
We meet a confusion, these days, As code 128 font is used in label printing, the font is installed in the PCs, but when PC re-installed, different code 128 font with same font face name (both name "Code 128") can be installed at same PC, as different algorithm related with individual code 128 font, and the only proper algorithm can match with the correct barcode to be identified by the scanner, it cost us lot of time to find the correct font file as fonts has slight difference. whether there is a solution to use local font file (locate in application folder) rather than use the font face name installed in the window system as some Web site.
I don't know whether there is any functionality for loading a font for PS mobile applications.
