pure speculation, but I will put it out there just in case: first, v15 is 32-bits and carbon, v17 is 64-bits and cocoa. so there is a massive difference there.
then, evidently the print option "Hide printing progress option" is no longer supported in 64-bits, http://doc.4d.com/4Dv17/4D/17/SET-PRINT-OPTION.301-3730865.en.html which makes one wonder if interactive or progressive (from code perspective) printing is not allowed by the system. not sure if running in a background preemptive thread can make any difference. in general, printing on the server is not recommended, which is why Microsoft intentionally ships the server edition of their OS without printing features. back to Mac, would it work if you first produced PDF on disk and then send that file to the printer (maybe using CLI/CUPS) in question? 2018/09/19 22:37、James Brown via 4D_Tech <[email protected]<mailto:[email protected]>>のメール: Has anyone had a similar experience? Any idea what could be causing this with v17? ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
