High Virgil >Only thing I could think was that it must have got confused somehow as >I've never seen somebody run 4 at one time on one pc via USB.. I ran into precisely this problem a couple of weeks ago. My app needs to print on 4 different preprinted forms at the same time and then, three copies of each form. I implemented a chain of 5 laser printers hooked to one PC and they all work via one USB switch. (the reason I have 5 printers is because some folks need to print and additional sheet, with a summary of all transactions and... well it is complicated) The fact is that I have 5 laser printers set up as a chain and they are all controlled by one PC. I had the problem that the printers were "confused" and printed randomly all forms on the same printer, driving me nuts, until after some consultation in this forum and a lot of head scratching, came up with a very simple solution: Put a wait statement between sheets (actually INKEY(2) ). The reason: apparently the microprocessor in the PC is so much faster than the capacity of the USB port to deal with the data that it would not switch to the correct printer as the program commanded (incidentally this had happened to me in the past with impact printers in FPD and the solution was to put a do while loop like this: w=1 do while w< 100000 enddo ) My present solution, which works like a charm with the lasers has been posted here but I will repeat it anyways. _pcopies = 3 _peject='NONE' set printer to name \\facturacion\listas printjob Report Form listas to printer noconsole =Inkey(2) endprintjob _pcopies = 3 _peject='NONE' set printer to name \\facturacion\remitos printjob Report Form remitos to printer noconsole =Inkey(2) endprintjob etc As you see, the wait command (inkey) will give the USB port 2 seconds after printing each page, which is time enough for the next set printer command to work Regards Rafael Copquin [excessive quoting removed by server] _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
