Re: [Gimp-user] Printing a poster file issues

["Rick Strong" <rnstrong primus ca>]

1. Save your original and then save a copy under a new name.
2. Flatten it. Check that your photo is no more than 300 dpi.
3. Do Image > Scale Image and scale it down to the size you will print out 
at on your home printer i.e. A3. Make the pxi 300.
4. Save to PDF.
5. Print the PDF.

Can someone tell me if the file sizes I am experiencing are to be 
expected--YES
Should I be able to print a PDF this size out?--NO, NOT AT HOME.
Can anyone see anything that I am doing wrong?--FILE IS TOO BIG FOR YOUR 
HOME PRINTER.
Can anyone suggest how to get my PDF file out--SEE ABOVE
and that will be able to be printed when sent to the printer?--SEND YOUR 
PRINTER A FLAT FILE, AT THE LARGE SIZE.
Would a professional printer have some sort of software that will allow them 
to print a PDF  that I can't print?--YES

Subject: [Gimp-user] Printing a poster file issues

Please go easy on me as I have not done anything like this before and I am 
sure
I am making a stupid mistake somewhere.

I need to create a poster that is roughly 1.3m x 2m and the printer requires 
at
least 300 DPI.

I have created my poster in GIMP and it consists of 7 layers - x1 large 
picture
that fills the poster and several other small logos/pictures/text.  The 
pixels
per inch setting in GIMP was set as 350.

The GIMP file is roughly 687Mb and when I export it to a PDF the PDF file is
roughly 375Mb.

When I try to open the PDF file in Adobe Reader DC I get an error - out of
memory and the file does not open.

GIMP version - 2.8.18
Adobe Reader DC version - 2015.020.20042

When I export to PDF from GIMP I ensure that the options to ignore hidden 
layers
is ticked and also that the option to convert to vector data type if 
possible is
ticked.

After getting stuck here I removed the hidden layers from the GIMP file ie
deleted them - they are used for alignment and information when designing.
After this the file size was very slightly smaller and Adobe Reader could 
open
the file.  However when I tried to print it out in A3 sheets to check to see 
how
it looks Adobe hung up on the flattenning stage.  So I then went back to 
GIMP
and flattened it in GIMP so that everything was combined into one layer. 
Now
when I go back to Adobe to print I have no hanging up on flattening however 
it
hangs up on "print 0%".  When I check the task manager Adobe is using up 
plenty
of processing so it is doing something...

Having no experience in doing something like this I dont know if the file 
sizes
involved are "normal" or not.

Can someone tell me if the file sizes I am experiencing are to be expected - 
I
would assume they are.
Should I be able to print a PDF this size out?
Can anyone see anything that I am doing wrong?
Can anyone suggest how to get my PDF file out and that will be able to be
printed when sent to the printer?  Would a professional printer have some 
sort
of software that will allow them to print a PDF  that I can't print?
