What are the escape sequences that I should use in order to print barcodes
with format Code 39?
What should be the sintaxis of the commands using Progress 4GL

I am not sure what barcode printing has to do with MobilRead
1) Your printers have no native support for Barcodes.
2) also, Dot-Matrix printers make lousy barcodes when the ribbon is new, and non-functional barcodes when the ribbon is partially worn. (Scanner can't read)
3) Laser printers can make nice barcodes, burt durability is short lived. The toner rubs off and the "good read" rate drops into the DM range
4)Inkjet printers can make barcodes, but the paper must prevent Ink bleeding or the lines smear
5) Direct Thermal printers make excellent labels (when the print head is cleaned regularly), and the labels last quite a while when not exposed to SUN or long term fluorescent lighting (they turn brown). (UPS aqnd FedEx boxes use these a lot).
6) Thermal transfer are the long lasting labels (P-touch labels are this type). The Thermal ribbon slows the printer down, some what and is an added cost, so usage, determines if you use Direct or Transfer. Most roll fed Thermal transfer printers will accept (do check to be sure) the cheaper direct thermal labels.
There are some add on (boards or In-line (between the cable and the printer) for non-native barcodeprinters.
There are True-type fonts for Code39 and other popular codes. Code39 have an Astrix as the start and stop chars *your-text* in addition to the printer/module specific commands.
