Running from within a COM server : error # 125 ('Printer is not ready') at line 7738 of foxyPreviewer.app


Hi all,

Trying to print reports as PDF using FoxyPreviewer:

do foxyPreviewer.app fails at server startup:

_REPORTOUTPUT = 'ReportOutput.app' && in _Libs\FoxyPreviewer\ in production
do foxyPreviewer.app && in production mode, error # 125 ('Printer is not ready') at line 7738 of foxyPreviewer.app

full server startup source code is here:

here are the default printer security settings:

Important note: 2 COM servers instances are running, it may have an influence on the outcome:

Any advice ?

Salut Thierry,

Unfortunately, I have no experience in running FoxyPreviewer with COM servers.
AFAIK, the REPORT FORM command is not supported in COM servers????

Oi Cesar,

REPORT FORM command is not supported in COM+ (dll) VFP automation servers, and supported in COM (exe) VFP automation servers, and this is what FoxInCloud (and Web Connect) use.

Strangely this error sometimes does not occur - I remember once being able to run a report with FoxyPreviewer in COM mode during my tests.

Do you know any printer setting that we could tamper around?

Did some more research, line 7738 seems to be in FoxyInitForm.Init():
m.loHelper = CREATEOBJECT("PreviewHelper", .T.)
I think it fails on:
cPrinterName = SET("Printer",3)
I've checked on the server: opened a VFP IDE and executed SET("Printer",3) in the command window: observed a slight delay first time, no delay on subsequent calls.

After this I restarted the exe COM server: OK, no error

Maybe a COM server does not accept waiting until printer is ready.

Testing this workaround:
Sys(13) && 2016-10-12 thn -- {FiC V 2.22.0-beta.8} {en} added as workaround to error # 125 ('Printer is not ready') at line 7738 of foxyPreviewer.app - https://foxypreviewer.codeplex.com/workitem/10921

do foxyPreviewer.app
Will report whether it works

Sys(13) does not seem to fix the issue consistently;
sometimes work, sometimes does not.

opening a session on the server and viewing the printer's property seems to be a valid, though unpractical, workaround.
