I encounter error | Please avoid changing print job |
“Cannot open port | parameters (via LPR GUI, for example) |
device file” when | while a print job is in progress. Known |
printing a document. | versions of CUPS server cut off the print |
| jobs whenever print options are changed |
| and then try to restart the job from the |
| beginning. Since Unified Linux Driver locks |
| port while printing, the abrupt termination |
| of the driver keeps the port locked and |
| therefore unavailable for subsequent print |
| jobs. If this situation occurred, try to |
| release the port. |
