If so, check out its manual, and determine the communication parameters; set up the serial port used to communicate to it (within gambas), then send every line you want to print to that serial port, followed by a CR and a LF: chr$(13) and chr$(10).
Using SHELL and /bin/lp is perhaps more simple but far less versatile and very slow (for what it can count speaking about printers...). /bin/lp (or /usr/bin/lp) is intended for a higher level usage, and it could be difficult to explain to it that you *don't* want to eject a page, you *don't* want to print if the printer is off-line, you *don't* want a banner and so on. By sending special characters and/or escape sequences you can take advantage of some printer features (may be your printer has a cutter, or other equipment). Probably it can do also graphics, barcode and more, but this is more difficult. Regards, Doriano ------------------------------------------------------------------------------ Come build with us!
