9/11/2023 0 Comments Mac os preview print slow![]() PDF to a PostScript-capable printer - pdftopdf → pdftops: at first glance, this might appear trivial, but the pdftops filter has to go through Ghostscript to re-render each page as PostScript.Here are some examples from systems and printers I have around the house: It's very difficult to make PostScript - a Turing-complete programming language - secure, while PDF doesn't require these language features (aside from it supporting embedded JavaScript) and can be less of a security issue.ĬUPS has some useful debugging features (there are some guides to them here: CUPSFilter and here: CUPSDebugging) which shows you the filter path. ![]() CUPS hasn't used PostScript as its transport format internally since at least late 2011. That might have been the case some time ago, but it's not true now. There are two types of drivers: postscript and non-postscript If you use a non-postscript driver, PDF files print slower. Their wireless is pretty useless on their printers. They sometimes take forever to print, and sometimes it doesn't work at all regardless of platform/computer by wireless. In addition to this, he is using a HP printer and did not tell us if he is trying it wirelessly, or through the USB. And some of them are on the default list, otherwise you have to install the hp library by their package (HPLIP) either through the software depository via APT or from HP. The probable reason why its printing slow is that it is rendering each page as a graphic, then printing it at 360-2400 DPI depending on what DPI setting the graphics printer mode is set.ĬUPS can install both types (graphic or postscript). The reason why I told the OP to look for a postscript driver is that it would read the PDF and print because PDF files are written in postscript format, so there would be no conversion and print fast. Some printers understand image formats like JPEG, and CUPS will pass those through directly if it can CUPS converts almost everything¹ to PDF for printing anyway, so even if you're printing a Word document from a laptop via your Raspberry Pi, your Raspberry Pi sees it as a PDF coming into CUPS. Some PDFs are really slow to process, and this is where the extra processing power and memory of the laptop win out over the Raspberry Pi's rather more modest capabilities. Presume you are connecting the printer via USB to the Raspberry Pi ? Since Dec 2020 Raspberry Pi with Desktop (Raspbian Buster) Operating System release, printing support has been included by default, The guide you linked to is 7 years old and seriously out of date, actually any guide not 2021 is likely not worth perusing. Is there any way that i could speed up the process of printing the pdf files, please? docx format, it gets printed in a lot less time that the >5minutes of the pdf. ![]() Through the CUPS if i send the same file in. If i attach the printer via usb to the Laptop (Win10) takes around 30 secs to print the same file. For example 10 pages pdf takes more than 5 minutes to get them printed. The problem i have is that when sending pdf files, it takes ages. I got a usb multifunction machine (fax, printer, copy) HP Deskjet 3830 and it is attached to my Rpi and it is shared in the network.
