Hi guys, I wanted to know if the problem reported to the spool has been corrected Andrew wrote this:
I want to know if this change is already planned. As the printer by printing directly onto print appears to be very slow. Thanks. Daniele

The printing is certainly slow, but I'm not convinced that the size of the document is the real problem. Printing speed has been a problem with this library since day one and it is always the first thing I test when I get a new release. I just tested with version 8.15 and the results are confusing. If I print directly using QuickPdf.printdocument a four page document I have shows in the printer dialog (HP LaserJet 1320 TN) as being 8.68 MB in size. QuickPdf renders that to the printer in just a few seconds and then it's job is done. The printer then takes about 4 minutes to print that 4 page document! If I have QuickPdf render the document to a stream one page at a time and then load that stream into a third party imaging component (ImageEn http://www.imageen.com ) and have the ImageEn component print the document one page at a time, the process takes slightly longer and the printer dialog shows the document size to be about 120 MB. However that entire process from start until printing is finished takes about 20 seconds as opposed to the 4 minutes for the QuickPdf document to print. So I don't really understand what is taking so long, but it is obviously more involved than just the size of the image being rendered. Harry |

finally someone who has the same problem ... I thought you were only using the PrintDocument method :) Yesterday I contacted technical support via this link http://www.quickpdflibrary.com/support/support-query.php surely those who work for the library already has in mind the problem. We can only hope that the problem is resolved in the next release, also because the programmers have done a great job and it would be a shame to lose this functionality. Thanks Harry

I have a very similar issue too, when the file is sent to the printer it takes time for each page to be processed before it is printed - I've counted about 6s per page. Will try converting each page to EMF and then printing that to a printer direct to see if there's any difference.

| I wrote a custom print function that loops through each page, exports them as EMF format to a stream and then using TMetaFile StretchDraw's it to a printer canvas and the print speed is instantaneous compared to using the PrintDocument functionality. |

Still same problem. Customers have been complained about slow print. No matter if Windows7 or XP. Delay is about one minute per page. Have you got anybody an idea how to solve this problem? We use last release 9.11 Thank you. thrash |
