I have a PNC1000 with both serial and parrallel ports. ... Although it is listed as the driver for the PNC1000. I set it up for LPT1. When I say print it shows up in the print que as printing then a short while later it says it failed. Is there any settings that would make the unit totally unresponsive or would setting errors in the software still cause it to do something even if it is not correct?
Is there a diagnostic for testing the ports as that seems to be the only thing left that could have failed on this unit. Thanks.
There are 2 possible hardware computer cable causes why your PNC1000 is having problems communicating with the computer...
1.) One problem is caused by Roland not updating their older PNC printers/cutters software drivers to use newer USB to Centronics parallel cables. When starting a print/cut job, the computer sends a data stream through the USB Parallel cable to the PNC-1000 series Cutter and fills the Cutter's memory data buffer. At first, the Cutter seems to work OK cutting the print job and then abruptly stops and seems to freeze..
The Roland printer driver software for older PNC printers/cutters is not tested nor written to work with USB Cables that transfer some but not all data signals between computer equipment, which is why the print job abruptly stops. In other words, the older parallel cables can
both send and receive data signals to/from the computer and Printer/.Cutter. However, the USB to Parallel Cable can
only send data from the computer to the printer/cutter and cannot receive data requests from the printer/cutter.
Please excuse my detailed explanation... This problem is caused because the older PNC-1000 series print driver thinks it is sending a return ACK signal requesting more data to be refill the memory buffer through an older fully wired parallel cable to computer. However, the printer driver does not realize it is using a newer USB Parallel cable that is not programmed to format nor send a return ACK signal back to the computer. The PNC printer driver then waits for a return signal it never receives and seems to freeze waiting for a response.
2.) The second problem is some of the cheaper parallel or serial cables used to connect the computer to the PNC1000 printer/Cutter may not have all of their adapter connector pins soldered . The computer cable manufacturing companies tried to cut production and materials costs by reducing the number cables and/or connectors with a computer data cable. These computer cables with fewer pins and connectors often do not work with older printer drivers that are lookin for more pin connections. Many times, these cable manufacturing companies will only guarantee the cables use with basic Windows print drivers included with the Windows OS and NOT GUARANTEE that computer cable's use with OEM printer/cutter custom drivers that require full cable connections.
