Printing on Windows CE

Printing on Windows CE

Is it possible to print on Windows CE devices

Printing on Windows CE is only possible with many limitations.
on Windows CE, no dedicated printer spooler is available. Therefore printing is a task which is performed in the foreground, blocking all other applications. Also it is not possible to "install" printers on Windows CE. If the CE Device manufacturer did not include the printing feature in its image, printing is generally not possible. If something is being printed, it is not possible to select a printer. It is just being sent to the default printer.
A program to configure the default printer on the CE device is only very rarely available. Mostly a workaround by printing through pocketword can be used to configure the printer. If printing is not available or if the desired printer is not configurable or working, the chances to get the printing to work on Windows CE are very minimal.
printing on Windows CE from within zenOn is also only limited supported. Printing a hardcopy for example is not available, so no trend can be printed.
The following printing features can be used on Windows CE:
- online printing of Alarms / online printing of the CEL
This printing mode is exclusive. Meaning it can only print either the alarms or the CEL online. Online printing of Alarms and CEL on Windows CE is only possible with a Line-Feed capable printer (like Epson LQ 850) and is being sent directly to LPT1. (the CE device must have this port of course!) This type of printing is implemented in zenOn and prints directly to the LPT port without using the printing capabilities of the OS. Thus not blocking the runtime.

- offline printing of Alarms / CEL
Prints offline alarm / CEL lists to the default printer configured in the OS. Printing is very slowly due to the limited performance of the CE devices. The Print is printed as a graphic (supports ttf fonts) and therefore every page must be completely calculated as a bitmap in the memory. Of course the memory available must be sufficient. The printing blocks all other applications on the device

- print current values
Prints current values of variables configured in the .frm file to the default printer. Also here printing is very slowly and the printing blocks all other applications on the device.
