Ciao,

I work with a seaside application.

I would to hear that. I wish your success.

I have a printer device and i need to manage the use of it at one work at time.

I think to use one Semaphore forMutualExclusion defined as variable of the specific printerTicket device

Now i defined this code to mange the access :

aPrinterTicket accessSema critical:[

Transcript show?

stampaok:= [ " i open a IP connection on the device. do the printer and manage relative errors " TicketBaseTipoCentriCarico newOn: dcmModel dettagli: tfDettagli onPrinter: aPrinterTicket ]

on: Error do: [:ex | " for error i open dialog to advise the operator " self jqDialog: (DTRCassaDialogConferma openOnException: ex onModel: dcmModel).

" repeat until the printer is do without error " ex retry ] ].

where do you execute stampaok I do not see a value.

" When the printer is do i advise the operator of it and allow the next request " stampaok ifTrue: [self jqDialog:(DTRCassaDialogConferma openOnModel: dcmModel) title: 'Ordinazione confermata']. ]

With this code the printer semaphore don't work.

The semaphore don't manage the code of the request,

did you try to put a transcript

and when i have a error, at any loop the excessSignal of the printer semaphore is incremented.

Any idea ?

Thanks,

Dario
