Calamus runs in WindowsPack under a built-in emulator. This makes
it possible for Calamus to run on Windows computers by emulating a TOS
operating system. Due to this Calamus is a little slower than on a
TOS-compatible computer or on an Apple computer with MagicMac. This is
because the TOS processor instructions have to be byte-swapped
completely each time so that they can be understood by the Windows PC
processor – instruction by instruction, over and over again.
This alone slows things down in comparison to an operating system
where this byte-swapping of functions is not necessary. For this
reason the emulator is assigned under Windows to work with a sensibly
chosen (high) priority. Because – unlike other Windows
applications – it doesn't really know when you are
working with Calamus or when Calamus is simply
If you now use Calamus to print out a file via WinPrint, then the following happens as a rule:
During this process there are a number of places where problems
can arise, which you can solve yourself. An important role is played
Calamus parameters dialog here, which you can call by
holding down the [Ctrl] key while launching Calamus.
If possible, do not assign more memory to Calamus than is actually present in your PC. It is possible to assign more (depending on the amount of free space on the relevant hard disk), but the WindowsPack emulator then has to swap back and forth continuously between physical RAM and the hard disk. This does not exactly speed up the process!
Calamus can tell the Windows printer spooler that it should accept a file as completely received only after xx seconds. But sometimes it may happen that the printer spooler is set to a very low timeout value, and with a very large page, which is possibly being printed from Calamus in colour, starts to print the page while Calamus is still sending data to the printer spooler. In that case set the Spooler wait time in the Calamus Parameters dialog to a higher value, say to 60 or 120 seconds.
As already described in the introduction to the WinPrint
printer driver, Calamus always runs with a very high priority. When
you have printed a page in Calamus, it may be advantageous to
minimise Calamus, in other words click at top right of the
window containing Calamus on the minimiser icon so that Calamus only
appears in the Windows taskbar. Then the Calamus
be set to the lowest priority under Windows – provided that you
have set the
Save CPU time when minimized switch in the Calamus
Parameters dialog. In that case the Windows printer spooler can pass
the data it has received at full speed to the Windows printer driver,
without being slowed down continuously by Calamus.
