CUPS 支持哪些文件格式？
CUPS 支持的文件格式的完整列表是什麼？（即我可以直接輸入哪些文件類型
lpr而無需先轉換它們？）我一直在尋找答案，但沒有找到任何具體的答案。我能找到的最好的是“ CUPS 可以直接理解許多不同類型的文件，包括文本、PostScript、PDF 和圖像文件。 ”但這仍然相當模糊；特別是，它接受哪些圖像文件格式？
謝謝！
CUPS 使用MIME 數據庫來確定它可以執行哪些文件轉換。
數據庫由
*.convs和*.types文件組成。這兩個都有手冊頁：cupsd 手冊頁列出了這些文件的位置：
/usr/share/cups/mime/mime.convs/usr/share/cups/mime/mime.types中通常有額外的 *.convs 和 *.types 文件
/usr/share/cups/mime/，cupsd 也使用這些文件。在我的 Slackware 14.2 系統上，我得到以下資訊：
$ grep -h "^[^#]" /usr/share/cups/mime/*.convs | sort application/msword text/vnd.cups-brf 30 texttobrf application/octet-stream application/vnd.cups-raw 0 - application/pdf application/vnd.cups-pdf 66 pdftopdf application/pdf text/vnd.cups-brf 100 texttobrf application/pdf image/tiff 80 pstotiff application/postscript application/vnd.cups-postscript 66 pstops application/postscript application/pdf 0 pstopdf application/postscript image/tiff 80 pstotiff application/rtf text/vnd.cups-brf 30 texttobrf application/vnd.adobe-reader-postscript application/vnd.cups-postscript 66 pstops application/vnd.cups-pdf application/vnd.cups-postscript 100 pdftops application/vnd.cups-pdf application/vnd.cups-raster 100 pdftoraster application/vnd.cups-pdf application/vnd.cups-raster 99 gstoraster application/vnd.cups-pdf image/tiff 80 pstotiff application/vnd.cups-pdf-banner application/pdf 32 bannertopdf application/vnd.cups-postscript application/vnd.cups-raster 175 gstoraster application/vnd.cups-postscript image/tiff 80 pstotiff application/vnd.cups-raster image/pwg-raster 100 rastertopwg application/vnd.openxmlformats-officedocument.wordprocessingml.document text/vnd.cups-brf 30 texttobrf application/x-cshell text/plain 100 -

cupsfilter您還可以通過直接呼叫文件和--list-filters選項（不會列印文件）來查看轉換將使用哪些過濾器：$ cupsfilter --list-filters foo.png imagetoraster rastertopwg rastertopdf（注意：我通過 設置了預設列印機
lpoptions，因此我不必提供列印機名稱。如果必須，您可以cupsfilter使用-d選項將列印機名稱傳遞給。）
