explain in more detail my objection to flip/orientation specification in the

<p class=MsoNormal><font size=3 color=blue face=Cambria><span style='font-size:
12.0pt;font-family:Cambria;color:blue'>All printers should be able to consume (PWG)
Raster but it more likely that most mid and higher end printer will consume
PDF. It is also more likely that it will be lower end printers, those
with limited resources, which will directly consume (PWG) Raster. Since
by definition they have limited resources it would be burden to have these
printers perform flip/orientation transforms that require very large buffers
that would basically have to hold an entire page worth of raster data. (example;
a typical Epson inkjet can print width is US Legal and has a specified maximum
page length of 44 inches. Lets assume we are just talking 24 bit
RGB data on legal size media at high quality print DPI of 1440v x 2880h or 8.5*2880*3x1440*13
or about 1.3 gb. Big and expensive. For larger media size and if
CMYK or CMYKLcLm data was sent to the printer we are talking very large
buffers. I am not sure if a printer has to support all of color-spaces
defined in the (PWG) Raster; but the largest on is 30 byte per pixel!!! That
really big and expensive. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 color=blue face=Cambria><span style='font-size:
12.0pt;font-family:Cambria;color:blue'>In the old days, when there were printer
drivers; they handled producing raster content for the target printer in the
orientation the printer needed. In the new order of things, where there
are no printer drivers; it is up to the producer of the raster to put the
content in a “standard” format for printer and not to expect the
printer to perform additional transforms the raster content. <o:p></o:p></span></font></p>

must be targeted to specific printer or at least printer model. If
the print-job is re-targeted to a different printer then the raster may
have to be regenerated to the new target printer.<o:p></o:p></span></font></li>

color=blue face=Cambria><span style='font-size:12.0pt;font-family:Cambria'>The
Alternate to the above is the raster producer will orient and flip the
print content exactly the same for all printers and based solely on the
user print intent. Then it is the print vendor issue to consume this
standardized format and ensure the correct output is obtained. In
this case, there is no need to put this information in the raster header
since it has no meaning or value to printer.<o:p></o:p></span></font></li>

better the need for flip/orientation in a raster. Since I do

would it be possible for you to send an email to the individuals who requested
the flip/orientation asking if they can state why they need the data and why
they are not expecting the raster to be in the correct flip/orientation that
the printer would need to print the specified print job. <o:p></o:p></span></font></p>
