Hi, I guess it is because you are printing to a raw device (/dev/lp0) which has no buffering. Two paths for you to follow:
Install (and probably modify) a printer driver such as 'generic' through CUPS. This will introduce a buffer to the printing process. or Use a (very) un-subtle workaround: trap the error. Loop on a 0.5 sec (or whatever) delay and try again. I call it the Stalinist approach. Its a bit like getting people to continually vote on a constitution until they get the right answer. rgds -- View this message in context: http://www.nabble.com/Ask-About-POS-Programming-using-Gambas-tp21345920p21346777.html Sent from the gambas-user mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Check out the new SourceForge.net Marketplace.
