Hi,
I have written a PCL 5c driver, it is based on the Microsoft Unidriver.
When I do a “print to file”, the .prn file size is sometimes more than 100
times the actual file size !!!.
Is there a problem with the Unidriver ?. Can we reduce this file size ?.
When I opened the .prn I found that the compression techniques has been used
but still the file size has gone so big.
Regards,
S.Sriram
That is probably due to all the PCL commands specified in the GPD file.
Also, it can depend on what you specify in your GPD. For example, if you
write your GPD to produce a raw raster image dump of whatever you are
printing including white pixels, the output will be larger than you
expect. It can also depend on the kind of font support your GPD
specifies.

Ashwin,
I don’t think the problem is with the GPD. When I try to print it to a file,
the file size is very big, but when I print it to a printer directly the
file size if very less.
I used a power point slide for testing, when I printed to a file, the file
size was 3MB, but when I printed directly, I saw the spooled file size was
40KB !!!.
What could be the difference between printing to a file and directly
printing ?.
Regards,
S.Sriram

You cannot compare the spool file size to the actual output size. The
spool file is probably in EMF format and the rendering hasn't even taken
place at the time of spooling. So that comparison does not hold.
The output size can depend on numerous factors like:
The above points are just a few factors that can affect the final output
size. So it really depends on what you specify within your GPD because
this is what controls the various code paths within unidrv.

Ashwin,
You were correct, everything was getting printed in raster. We added support
for Vector graphics and then found the file size reduced drastically.
Thank you.
