I hate to say this but you should really ask the printer for this; he'll tell you what's the max he can print at. If you speak with their prepress department and the printer operators, they'll really tell you in details what's the best process. Don't waste your time with the sales department, (no offense to salesmen) they usually repeat the same cassette ...
The dialog box is very clear: File > Export bitmap In the dialog box choose units: Inches Below will say: width: 600, height: 600 (this is the size in pixels) and little to the right will say 300 ppi. (this is the print resolution) The math behind it is very simple 2 inches, at 300 pixels each inch = 2x300 = 600 px.
The "pixel" unity in SVG (or CSS) files is for reference only. Your image is never using actual pixels - they do not exist in vector formats such as SVG (the internal representation of Inkscape) or PDF files. (Check the pixel defintion in CSS here) So, if you want your resulting image to be 210x297mm in size (A4), set this size in your document ...
This is unfortunately something Inkscape cannot do. It sounds like what you're asking for is to have the image to have two difference sizes at once. Inkscape doesn't allow you to set the DPI of a PDF during export (the setting in the export window is the DPI for rasterizing filter effects, not the artwork itself), so you're stuck at 90 DPI. The solution I ...
Your printer probably meant that at this dimension (1000x98 pixels = 5.5" x 0.5" @72ppi), your artwork needs to be at least "600dpi". He wanted a 5.5" x 0.5" at 600dpi. Printers rarely use "pixels" for dimensions, they use the standard metric or imperial system as units (inch, centimeter, etc.). They often use dpi and ppi to mean the printed ...
As Rafael points out, 300dpi is the same as 118dpc (dots per centimeter?) Note that 300dpi is 'standard' for printing photographs. If your Artwork is text or line-art based, however, you want to be printing at much higher resolutions. 600dpi at minimum (if not higher at 1200dpi for high quality printing).
Just to let you know, ppi is used for web, and dpi for print. For exporting the regular values are 72 ppi for normal, 325 ppi if you have retina displays in mind, and 300 ppi for print, some printers can take higher, but normal ones 300 is enough.
The unit is 300 ppi. So if you convert it to cm you need to divide 300/2.54=118.11 ppcm. Use 118 ppcm or 300 ppi. But try not to use Photo-IUsethisProgramForAllButIShouldNot-Shop, but a vector based one, like Ilustrator, Corel, Inkscape, Scribus, Indesign, Serif Page Plus.
