LBP2900 Multi/once - page printing error

[Nomad192]

! Warning, I am using a translator !

Hi, thank you very much, now I can use LBP 2900 on ubuntu-server 22.04!

I have some problems printing multi-page documents (no matter website, pdf or word). When you try to print, sometimes an empty page is printed, and after it the button lights up red (blinks), if you click on it, the printer will finish printing the document. This does not always happen. Maybe you know the solution to this problem. Thank you very much!

Glad that you could get your printer to work!

I ran into this problem with an unreleased version, and it was found to be caused by incorrect page settings: the length of the raster was too long to fit on the page. In my case, the blank page never appears before the first page.

Maybe there is an oversight in the page setting routines (paper.c or the page_prologue functions in prn_lbp2900.c)...

Just out of interest, does this happen to the same documents all the time? If so, which paper size were you using, and what are the dimensions of the documents that were causing blank pages to be printed?

Hi, I'm afraid I can't trace the dependence of the file and the error, for the same site, he can print it both with and without an error, or with an error in another place. When such an error appears, CUPS says something like the following:

Created
Tue Sep 27 18:54:24 2022 
"Processing page 3..."

It also hung up once without blinking, in CUPS it was:

Created
Tue Sep 27 18:57:05 2022 
"Rendering completed"

Just in case, the paper size is a4, the problem has arisen at least once with each document that I tried to print, the size of the documents (if I understood correctly):
70k
348k
681k
914k

Thank you!

Hello, I just noticed the same problem for a single-page document! twice in a row...

I was talking about the target page size of the PDF when I mentioned "dimensions", which is the measurements you see when you open up the document properties in the PDF reader software. Were the PDFs 210mm x 279mm (A4 measurements), or were the measurements different?

This problem can happen when the page settings in the print dialog is set to US Letter, 215.9 x 279.4mm, (default in many apps and Fedora) and the printer is given A4 sheets. Blank pages should not appear if the sheet size is set correctly as the app should shrink the page raster to fit.

I will try to reproduce this problem on my LBP3000...

Hello, I looked at the documents, there are A4 pages everywhere, I tried to set the document to the page size clearly 210mm x 279mm, but when printing, the same problem arose again. (I printed using chrome A4 size, from a computer on a local network on windows, the printer is connected to ubuntu-server 22.04 with the use of CUPS)

Thank you so much again!

By the way, when I put the letter format in chrome, it started printing without this error...

UPD: To be more precise, the first time I print a document in letter format after A4format, the first page comes out empty, after that, no matter how many pages of documents I tried, everything is fine (in letter format)
