My conversations with two different vendors have indicated that using a Windows print driver requires Windows to store, scale, and bitmap the image before sending it to the printer. I guess this results in serious performance degredation, and can also cause problems with readability of the bar code. Since performance is pretty important to my application, I wanted to try to avoid that if possible... However, this sounds VERY intriguing: >2. Develope the Label Layout (with its software) and store it on the printer >then in R:Base I just say Out LPT/Serial and send the text commands to the >printer to fill in the data of the Layout. I didn't know you could do "output LPT/Serial". Is that an R:Base command? I thought it was only "output printer/screen/file"... I would think this method would have the lowest overhead, and provide the best performance... Is it difficult to send the ASCII data over a serial port to a printer? Does each printer have their own control languages? Thanks! --Wess P.S... Has anybody heard of a product called BarTender Enterprise? I understand it is software that monitors for a created text file and then uses it to start a label print job. I could use R:Base to write the file, and let that software serve it up for printing. They say it is pretty much instantaneous, but at $795, it's not cheap... ================================================ TO SEE MESSAGE POSTING GUIDELINES: Send a plain text email to [EMAIL PROTECTED] In the message body, put just two words: INTRO rbase-l ================================================ TO UNSUBSCRIBE: send a plain text email to [EMAIL PROTECTED] In the message body, put just two words: UNSUBSCRIBE rbase-l ================================================ TO SEE MESSAGE POSTING GUIDELINES: Send a plain text email to [EMAIL PROTECTED] In the message body, put just two words: INTRO rbase-l ================================================ TO UNSUBSCRIBE: send a plain text email to [EMAIL PROTECTED] In the message body, put just two words: UNSUBSCRIBE rbase-l
